- Page 2 INTRODUCTION Diagram 1 MicroSpeed 196 The MicroSpeed 196 is a closed-loop motion control device, designed to operate as a Back Panel Terminals: stand-alone Master, controlling a single AC, DC, or servo-type variable-speed drive of any horsepower; or as a Follower control in more complex multi-motor drive systems.
- Page 3 Stop, jumper and switch to common (Open = the MicroSpeed 196, except for the AC input power. The shields should be tied on one Run). Closed = When Run/Stop is used in this way, the front panel keypad RUN and end only.
- Page 4 This input tells the MicroSpeed 196 to operate independently (as a Master), or to follow the lead signal of another device (feedback from a lead motor or a generated signal from a PLC). The MicroSpeed 196 only reads this input while Master/Follower stopped in the Ready mode.
- Page 5 Variables”). The outputs are Open Collector NPN transistors, rated for 5OVdc, 250mA and .3-watt maximums. These outputs are intended to be used with the Microspeed 196 inputs, relays, LEDs, etc. Power to the output circuits should be wired parallel with the...
- Page 6 Programming THE VARIABLES: 18 Drive Enable The MicroSpeed 196 is programmed by entering data into a menu of variables. Only the Auxiliary Mode Variables- Allows for a third frequency, i.e., dancer variables that affect operation of the unit as it relates to the application must be...
- Page 7 PROGRAMMING FOLLOWER MODE The Microspeed 196 in the Follower mode mirrors a lead frequency input, and can be Program the following variables when using the MicroSpeed 196 in any mode. (These scaled by the Ratio Set Point. The lead frequency is typically generated from a digital are the only required variables if the MicroSpeed 196 will be used exclusively in transducer on another shaft.
- Page 8 TB1-12 to 0001 = Ramp on Decel TBl-11. 0010 = Ramp on Accel Note: It is recommended that you “lock out” your variables, so that the MicroSpeed 196 0011 = Ramp on Accel and Decel cannot be inadvertently reprogrammed. Positions:...
- Page 9 When Variable 22 is selected, the alphanumeric display will read Tach Sel. MicroSpeed 196 will be used in both modes. When programming the MicroSpeed 196 To select between the two follower display options, enter one of the following numbers: custom display, the Master/Follower input must be in the appropriate position.
- Page 10 Variable 18 - Drive Enable This output is designed to give the MicroSpeed 196 control of the Run/Stop input on the controlled drive or other MicroSpeed 196 ’s, Program the MicroSpeed 196 variables. based on the conditions it is monitoring. Drive Enable is actuated when...
- Page 11 100 will add 10 msec to the loop time this bit is added. Using the integral? - The MicroSpeed 196 in the Follower mode operates on a zero error basis. For every master pulse, the MicroSpeed 196 will attempt to force a Variable 14 - (D) Derivative (or Rate) -The Derivative operates as a boost to the corresponding follower pulse.
- Page 12 Delays the start of the Auxiliary Trim AC or DC Drive function on startup. Enter the number of 10 msec update cycles to wait. When ENTER is pressed, the MicroSpeed 196 will insert a decimal point to display the delay in seconds. MicroSpeed 196...
- Page 13 Send and Receive lines at the terminal Refer to Section VIII, “Programming the Display, ” for information. (RXD- to TXD- and RXD+ to TXD+). The MicroSpeed 196 tests its communication Diag. 1 - Keypad Test - In this test, pressing each key on the front panel keypad will circuitry to make sure it is functioning.
- Page 14 SERIAL COMMUNICATIONS VIA RS422 format have been received by the MicroSpeed 196. If the variable displays a 2, then transmissions have been sent to the MicroSpeed 196 faster than it can process the information and respond. The most recent error is kept in this variable until you set it to 0.
- Page 15 A global write command is allowed. the MicroSpeed 196. Character 2 is the 10's location and character 3 is the l’ s location. A node address of 00 is a Global Command. All MicroSpeed 196 units are affected Example: Write Node 27, Variable 02, the Data 15.00...
- Page 16 Master or Follower Mode (O=Master, =Follower) Start - 0 - Starts the specified MicroSpeed 196. If the front or back panel stop has been Closed or Open Loop (O=Closed Loop, 1 =Open Loop) enabled (with Var 30) and Stop is held, this command will be ignored.
- Page 17 The unit acts on a message but does not return a response. Using global commands without Node 1 on line. Not waiting long enough for response. The MicroSpeed 196 transmit lines are open or shorted. More than one MicroSpeed 196 with the same node address. Do a Diagnostic 6 communications test.
