Page 25: Chapter 3 I/O Interface
To construct a system utilizing the features of the ERCX series, you must understand the signals assigned to each terminal on the I/O connector and how they work. This chapter 3 covers this fundamental information.
Page 26: I/O Signals
3-1 I/O Signals I/O Signals The standard I/O connector of the ERCX controller has 48 pins, with an individual signal assigned to each pin. The following table shows the pin number as well as the name and description of each signal assigned to each pin.
Page 27: Input Signal Description
3-2 Input Signal Description Input Signal Description Input signals consist of 7 dedicated command inputs, 16 general-purpose inputs, interlock signals and an emergency stop input. * DI15 functions as the SERVICE mode input when the SERVICE mode function is enabled. In this case, 15 general-purpose inputs are available.
Page 28 3-2 Input Signal Description ■ Absolute point movement command (ABS-PT) This command moves the robot to an absolute position of a point number specified by DI0 to DI9 along an axis coordinate whose origin is defined as 0, at a speed selected by DI10 or DI11. (See "3-2-2 General-purpose input (DI0 to DI15)").
Page 29 3-2 Input Signal Description ■ Return-to-origin command (ORG-S) This command returns the robot to its origin position when the search method is selected as the origin detection method. When the mark method is selected, this command checks the return-to- origin status. NOTE Once return-to-origin is performed after the robot cable and absolute battery are connected, there is no need to repeat it even when the controller is turned off.
Page 30: General-Purpose Input (Di0 To Di15)
3-2 Input Signal Description 3-2-2 General-purpose input (DI0 to DI15) These general-purpose inputs are available to users for handling data input in a program. These inputs are usually connected to sensors or switches. These inputs can also be directly con- nected to a PLC output circuit.
Page 31: Service Mode Input (Svce)
3-2 Input Signal Description 3-2-3 SERVICE mode input (SVCE) When the SERVICE mode function is enabled, DI15 functions as the SERVICE mode input (SVCE). The SERVICE mode input is used to notify the ERCX controller whether the current state is a "SERV- ICE mode state".
Page 32: Output Signal Description
3-3 Output Signal Description Output Signal Description The output signals consist of 3 dedicated outputs (READY, BUSY and END) and 13 general-purpose outputs. In this section, terms "ON" and "OFF" mean the output transistors are "on and off". 3-3-1 Dedicated output The dedicated outputs are used for exchanging signals between the ERCX controller and an external device such as a PLC.
Page 33: General-Purpose Output (Do0 To Do12)
3-4 I/O Circuits 3-3-2 General-purpose output (DO0 to DO12) These general-purpose outputs are available to users for freely controlling on/off operation in a pro- gram. These outputs are used in combination with an external 24V power supply, to drive loads such as solenoid valves and LED lamps.

CAUTION Parameters not displayed on the TPB screen are automatically set or optimized to match the robot type when the robot parameters are initialized. You usually do not have to change these parameter settings. If for some special reason you need to change or check these hidden parameters, use any of the following methods.
Page 74 5-2 Parameter Description PRM4: Acceleration This parameter sets the acceleration. The controller will automatically set optimum acceleration according to the robot type and payload. Change this parameter when the acceleration is to be decreased beyond this state. Input range: 1 to 100 (%) Default value: 100 PRM5: Return-to-origin direction...
Page 75 5-2 Parameter Description PRM8: No. of conditional input points This parameter specifies the number of effective points for the third data conditional input for executing the JMPF statement of the robot language. For example, when the default setting is selected for this parameter, the four points from DI0 to DI3 are used as the conditional inputs for the JMPF statement.
Page 76 5-2 Parameter Description PRM13: Origin detection method This parameter is used to select the origin (reference point) detection method. There are two methods for detecting the origin: search method and mark method. The search method is further divided into the origin sensor method and stroke-end detection method.
Page 77 5-2 Parameter Description PRM18: Speed integration gain This sets the speed control gain. Typically, PRM17 and PRM18 should be input at a ratio of 3 : 2. Generally, the larger the gain, the higher the acceleration will be. However, if the gain is set too high, abnormal oscillation or noise might be generated, causing serious problems in the robot and controller.
Page 78 5-2 Parameter Description PRM23: Payload-dependent acceleration coefficient The value calculated from PRM0, PRM12 and PRM3 is set automatically for this param- eter. Default value: Depends on robot type. PRM24: Teaching count data (TPB entry) This is entered in the TPB and cannot be used. Default value: 0 PRM25: Not used Default value: 0...
Page 79 5-2 Parameter Description PRM31: Open-circuit fault detection level This parameter sets the sensitivity for detecting an open-circuit fault. The upper limit of this parameter is 254. The sensitivity lowers as the parameter value increases. Leave this parameter set to 255 if you want to disable this detection function. Input range: 1 to 255 Default value: 255 (This function is disabled.)
Page 80 5-2 Parameter Description PRM34: System mode selection This parameter specifies the system operation mode. When you want to use the ERCX controller in operating specifications that differ from normal mode, for example, to make it compatible with the conventional controllers, change this parameter as explained below. This parameter functions are allocated in bit units.
Page 81 5-2 Parameter Description Bit 3: Voltage check setting for system backup battery This selects whether to check the system backup battery voltage when the control- ler servo is turned on. In such cases where you want to operate the robot immediately even when the battery needs to be replaced, you can temporarily disable this voltage check.
Page 82 5-2 Parameter Description PRM39: No. of motor poles Default value: Depends on robot type. PRM40: RESET execution condition selection Selects the operation to be executed with the I/O reset command. Input range: 0 to 2 Meaning: 0: Turns on the servo and resets the program. 1: Switches the operation depending on the LOCK signal status.
Page 83 5-2 Parameter Description PRM42: I/O point movement command speed 2 This parameter specifies the movement speed (%) at which the robot moves when a point movement command (ABS-PT, INC-PT) is executed. When "type 3" (point teaching type) is selected by the I/O assignment setting, this param- eter specifies the jog speed at which the robot moves at a jog movement command (JOG+, JOG-).
Page 84 5-2 Parameter Description PRM44: Maximum speed setting This parameter sets the maximum motor revolution speed. Input range: 1 to 4500 (rpm) Default value: Depends on robot type. CAUTION Changing this parameter carelessly might shorten the robot service life or cause other problems. PRM45: Feed forward gain Default value: Depends on robot type.
Page 85 5-2 Parameter Description PRM49: Controller version 1 This parameter reads out the version information (1) on the control software in the con- troller. This is a read-only parameter. PRM50: Deceleration (Available with Ver. 13.33 or later) Use this parameter to reduce only the deceleration. When this parameter is left set to the default value (100), the deceleration is the same as the acceleration.
Page 86 5-2 Parameter Description PRM53: Zone output selection (Available with Ver. 13.50 or later) This parameter is used to select the output destination and output logic when the zone output function is enabled. The zone output is used to control the signal output when the robot's current position is within the specified range.

Page 115: Chapter 8 Robot Language
This chapter explains the robot language. It describes what kind of commands are available and what they mean. The ERCX series uses the YAMAHA robot language. This is an easy-to-learn BASIC-like programming language. Even a first-time user can easily create programs to control complex robot and peripheral device movements.

Page 117: Robot Language Syntax Rules
8-2 Robot Language Syntax Rules Robot Language Syntax Rules 8-2-1 Command statement format The robot language command statement format for the ERCX controller is as follows. When creating a program using the TPB, each command statement can be automatically entered in this format, so you do not have to be aware of this format while creating the program.
Page 118: Variables
8-2 Robot Language Syntax Rules 8-2-2 Variables Variable are used in a program to hold data. The following variables can be used with the ERCX controller. ■ Point variable P A point variable can contain a point number. It is used in movement commands such as MOVA and MOVI statements instead of specifying the point number directly.
Page 119: Program Function
8-3 Program Function Program Function 8-3-1 Multi-task function A multi-task function allows simultaneous executing two or more programs (tasks). The ERCX con- troller can execute a maximum of 4 programs at the same time. Since the multi-task function simultaneously executes two or more programs, the following process- ing can be performed.
Page 120: Limitless Movement Function
8-3 Program Function 8-3-2 Limitless movement function The limitless movement function allows multiple turns in the same direction along the robot axis. The ERCX controller incorporates the soft limit function that prohibits any robot motion which exceeds the soft limits specified by the parameters. This soft limit function is very useful for linear movement type robots such as FLIP-X series.
Page 121 8-3 Program Function ■ When the position data unit parameter is set to 3: When this parameter is set to 3, the current position is expressed in degrees (°) from 0 to 359.99 as a basic cycle. Therefore, even if the robot moves to the 360° point, that position sets to 0° (=360°) so that the robot can rotate continuously in the same direction.
Page 122: Robot Language Description
8-4 Robot Language Description Robot Language Description 8-4-1 MOVA Function: Moves to a point specified by a point number (Moves to an absolute position relative to the origin point). Format: MOVA <point number>, <maximum speed> Example: MOVA 51, 80 Moves to P51 at speed 80. Explanation: This command moves the robot to a position on the absolute coordinates whose origin position is defined as 0.
Page 123: Movf
8-4 Robot Language Description 8-4-3 MOVF Function: Moves until a specified DI number input is received. Format: MOVF <point number> <DI number> <DI status> Example: MOVF 1, 2, 1 The robot moves toward P1 and stops when DI2 turns on. Program ex- ecution then proceeds to the next step.
Page 124: Jmpf
8-4 Robot Language Description 8-4-5 JMPF Function: If the conditional jump input matches the setting value, program execu- tion jumps to a specified label in a specified program. Format: JMPF <label number>, <program number>, <input condition value> Example: JMPF 12, 3, 5 If the conditional jump input is 5, program execution jumps to label 12 in program 3.
Page 125: Jmpb
8-4 Robot Language Description 8-4-6 JMPB Function: Jumps to a specified label when a specified general-purpose input or memory input is ON or OFF. Format: JMPB <label number>, <DI or MI number>, <input status> Example: JMPB 12, 8, 1 Jumps to label 12 when DI8 input is ON. If DI8 is OFF, the program execution proceeds to the next step.
Page 126: Call
8-4 Robot Language Description 8-4-8 CALL Function: Calls and executes another program. Format: CALL <program number>, <number of times> Example: CALL 5, 2 Calls program 5 and executes it twice. Program execution then proceeds to the next step. Explanation: When repeating the same operation a number of times, the CALL state- ment is used as needed to call and execute the subroutine defined as a separate program.
Page 127: Wait
8-4 Robot Language Description 8-4-10 WAIT Function: Waits until a specified general-purpose input or memory input changes to a specified state. Format: WAIT <DI or MI number>, <input status> Example: WAIT 5, 1 Waits until DI5 turns on. Explanation: This command adjusts the timing according to the general-purpose in- put or memory input state.
Page 128 8-4 Robot Language Description 8-4-12 P Function: Sets a point variable P. Format: <point number> Example: Sets a point variable P to 200. Explanation: The point variable can contain a point number as a variable, which can be from 0 to 999. By using a movement command such as MOVA with a P+ or P- statement, the number of steps required to create a repeating program can be reduced.
Page 129: Srvo
8-4 Robot Language Description 8-4-15 SRVO Function: Turns the servo on and off. Format: SRVO <servo status> Example: SRVO This turns the servo on. SRVO This turns the servo off. Explanation: This command is used to prevent an overload on the motor that may occur if the robot is locked mechanically after positioning is completed.
Page 130: Orgn
8-4 Robot Language Description 8-4-17 ORGN Function: Performs return-to-origin when the search method is selected as the ori- gin detection method, or checks whether return-to-origin has been per- formed when the mark method is selected. Format: ORGN Example: ORGN Performs return-to-origin when the search method is selected as the ori- gin detection method, or checks whether return-to-origin has been per- formed when the mark method is selected.
Page 131: Ton
8-4 Robot Language Description 8-4-18 TON Function: Executes a specified task. Format: <task number>, <program number>, <start type> Example: 1,2,0 Newly executes program 2 as task 1. Explanation: This command starts multiple tasks and can be used to control the I/O signals in parallel with the axis movement and perform different process- ing for each axis.
Page 132: Jmpp
8-4 Robot Language Description 8-4-20 JMPP Function: Jumps to a specified label when the axis position relation meets the speci- fied conditions. Format: JMPP <label number>, <axis position condition> Example: JMPP Jumps to label 3 if the X-axis position is smaller than the point specified with the point variable P.
Page 133: Mat
You do not have to enter any data in p253 and p254 (when pallet number is 0). • The matrix definition contents are shared with each task. • Because only a single-axis robot is controlled with the ERCX series, the actual movement is linear even if a 2-dimensional matrix is de- fined.
Page 134: Msel
8-4 Robot Language Description 8-4-22 MSEL Function: Specifies a matrix where the robot moves with a MOVM statement. Format: MSEL <pallet number> Example: MSEL Points where the robot moves with a MOVM statement are calculated based on matrix data of pallet number 0. Explanation: This command selects a matrix and is always used with a MOVM state- ment as a pair.
Page 135: Movm
• The MOVM statement performs calculation on the assumption that the robot operates on the Cartesian coordinate system. • Because only a single-axis robot is controlled with the ERCX series, the actual movement is linear even if a 2-dimensional matrix is de- fined.
Page 136: Jmpc
8-4 Robot Language Description 8-4-24 JMPC Function: Jumps to a specified label when the counter array variable C matches a specified value. Format: JMPC <label number>, <counter value> Example: JMPC 5, 100 Jumps to label 5 when the counter array variable C is 100. Program execution proceeds to the next step except when the counter array vari- able C is 100.

Page 175: Safety Settings For Service Mode
10-4 SERVICE mode function 10-4-1 Safety settings for SERVICE mode Safety controls that work in "SERVICE mode state" are explained in detail below. ■ Limiting command input from any device other than TPB When the operator is working within the robot safety enclosure using the TPB, permitting any command input from devices (such as via I/O) other than the TPB is very hazardous to the TPB operator.
Page 176 10-4 SERVICE mode function ■ Prohibiting the automatic operation and step operation Running an automatic operation or step operation while an operator is working within the robot safety enclosure is very dangerous to that operator. (For example, when the operator is in the safety enclosure, a hazardous situation may occur if someone runs a robot program without letting the operator know about it.)
