2.7.7 I/O Signal Controls and Functions * ON indicates that the applicable bit signal is “1,” while OFF indicates that the bit signal is “0.” How the I/O signals used in the position/simple direct mode, half direct mode and full direct mode are controlled, as well as the functions provided by these signals, are explained below.
Page 58
(5) Servo ON command (SON) [PLC output signal] Ready (SV) [PLC input signal] When the SON signal is turned ON, the servo will turn on. When the servo turns on, the status indicator LED (refer to 2.4, “DeviceNet Interface”) on the front panel of the controller will illuminate in green.
Page 59
(6) Home return (HOME) [PLC output signal] Home return complete (HEND) [PLC input signal] Home return in progress (GHMS) [PLC input signal] When the HOME signal is turned ON, the HOME command will be processed at the leading (ON) edge of the signal and home-return operation will be performed automatically.
Page 60
(7) Positioning start (CSTR): Used in the position/simple direct mode [PLC output signal] The CSTR command is processed at the leading (ON) edge of the signal, upon which the actuator will move to the position set by the target position corresponding to the specified position number or by the target position channel of the PLC.

Page 62
(12) Zone 1 (ZONE1) [PLC input signal] Zone 2 (ZONE2) [PLC input signal] Position zone (PZONE) [PLC input signal] Each signal turns ON when the current position of the actuator is inside the specified zone, and turns OFF when the current position is outside the zone. [1] Zone 1, zone 2 Each zone is set by user parameters.
Page 63
(13) +Jog (JOG+) [PLC output signal] -Jog (JOG-) [PLC output signal] These signals are used as starting commands for jog operation or inch operation. If a + command is issued, the actuator will operate in the direction opposite home. When a – command is issued, the actuator will operate in the direction of home.
Page 64
(14) Jog-speed/inch-distance switching (JVEL) [PLC output signal] This signal is used to switch between the jog speed parameter when jog operation is selected, and the inch distance parameter when inch operation is selected. JVEL signal Jog operation: JISL = OFF Inch operation: JISL = ON Parameter No.
Page 65
(16) Teaching command (MODE) [PLC output signal] Teaching mode signal (MODES) [PLC input signal] When the MODE signal is turned ON, the actuator mode will switch from normal operation to teaching. Upon switching to the teaching mode, the controller of each axis will turn the MODES signal ON. Program the PLC so that teaching operation will be performed after the MODES signal turns ON.
Page 66
(19) Operation mode (RMOD) [PLC output signal] Operation mode status (RMDS) [PLC input signal] The operation mode is selected as shown below based on the RMOD signal and the MODE switch on the front panel of the controller. Whether the current mode is AUTO or MANU can be checked using the RMDS signal. The combinations of RMOD signal and MODE switch settings and the corresponding operation modes are shown below.
Page 67
(23) Load missed in push motion (PSFL) [PLC input signal] This signal turns ON when the actuator has not contacted the load in push-motion operation after having moved the distance set by the “Positioning band” field in the position table stored in the controller or by the positioning band channel of the PLC.
Page 68
(26) Load output judgment (LOAD) [PLC input signal] [Dedicated PCON function] This signal is effective only during push-motion operation. To use the LOAD signal in a press-fit application, the controller must know whether the specified load threshold has been reached during push-motion operation. The load threshold and check range are set by the PLC, and the LOAD signal will turn ON when the command torque (motor current) exceeds the threshold inside the check range.
Page 69
(27) Torque level (TRQS) [PLC input signal] [Dedicated PCON function] This signal is effective only during push-motion operation. If the motor current reaches the load threshold during push-motion operation (= while the actuator is moving within the positioning band), the TRQS signal will turn ON. Since the level of current is monitored, the ON/OFF status of this signal will also change when the current changes.
Page 70
(28) Stopping control mode (SMOD) [PLC output signal] [Dedicated PCON function] One general characteristic of pulse motors is that their holding current at standstill is greater compared to AC servo motors. Accordingly, an energy-saving mode is provided to help reduce the power consumption in a standstill state in applications where the actuator remains stationary for a long period at standby positions.
Page 71
(29) Acceleration/deceleration mode (MOD1, MOD0) [PLC output signal] [Dedicated ACON function] These signals are used to select the acceleration/deceleration pattern characteristics. Select a desired mode before issuing an actuator move command. MOD1 MOD0 Pattern name Remarks Trapezoid pattern Factory setting S-motion Primary delay filter Not available.
Page 72
(30) Stop Mode Selection (ASO1, ASO0) [PLC Output Signal] Select the stop mode for the duration before the movement to the next position after a positioning is completed. If the duration for a stop is long, the system automatically turns the servo OFF to reduce the power consumption. Refer to the instruction manual for the controller for more information.
I/O Signal Timings The maximum response time after a control signal is turned ON to operate the ROBO Cylinder in a PLC sequence program, until a corresponding response (status) signal is returned to the PLC, is expressed by the formula below: Maximum response time (msec) = Yt + Xt + 3 + command processing time (operation time, etc.) Yt: Master station node transmission delay...

(13) +Jog (JOG+) [PLC output signal] -Jog (JOG-) [PLC output signal] These signals are used as starting commands for jog operation or inch operation. If a + command is issued, the actuator will operate in the direction opposite home. When a – command is issued, the actuator will operate in the direction of home.
Page 138

(19) Operation mode (RMOD) [PLC output signal] Operation mode status (RMDS) [PLC input signal] The operation mode is selected as shown below based on the RMOD signal and the MODE switch on the front panel of the controller. Whether the current mode is AUTO or MANU can be checked using the RMDS signal. The combinations of RMOD signal and MODE switch settings and the corresponding operation modes are shown below.
Page 141
(23) Load missed in push motion (PSFL) [PLC input signal] This signal turns ON when the actuator has not contacted the load in push-motion operation after having moved the distance set by the “Positioning band” field in the position table stored in the controller or by the positioning band channel of the PLC.
Page 142
(26) Load output judgment (LOAD) [PLC input signal] [PCON-CA/CFA only] This signal is effective only during push-motion operation. To use the LOAD signal in a press-fit application, the controller must know whether the specified load threshold has been reached during push-motion operation. The load threshold and check range are set by the PLC, and the LOAD signal will turn ON when the command torque (motor current) exceeds the threshold inside the check range.
Page 143
(27) Torque level (TRQS) [PLC input signal] [PCON-CA/CFA only] This signal is effective only during push-motion operation. If the motor current reaches the load threshold during push-motion operation (= while the actuator is moving within the positioning band), the TRQS signal will turn ON. Since the level of current is monitored, the ON/OFF status of this signal will also change when the current changes.
Page 144
(28) Stopping control mode (SMOD) [PLC output signal] [PCON-CA/CFA only] One general characteristic of pulse motors is that their holding current at standstill is greater compared to AC servo motors. Accordingly, an energy-saving mode is provided to help reduce the power consumption in a standstill state in applications where the actuator remains stationary for a long period at standby positions.
Page 145
(29) Acceleration/deceleration mode (MOD1, MOD0) [PLC output signal] These signals are used to select the acceleration/deceleration pattern characteristics. Select a desired mode before issuing an actuator move command. MOD1 MOD0 Pattern name Remarks Trapezoid pattern Factory setting S-motion Primary delay filter Not available.
Page 146
(30) Stop Mode Selection (ASO1, ASO0) [PLC Output Signal] Select the stop mode for the duration before the movement to the next position after a positioning is completed. If the duration for a stop is long, the system automatically turns the servo OFF to reduce the power consumption. Refer to the instruction manual for the controller for more information.
Page 147
(33) Vibration Damping Control Mode Selection 0, 1 (NTC0, NTC1) [PLC Output Signal] [ACON-CA only] The vibration damping control function suppresses the load vibration induced by IAI’s actuator. Measure the vibration frequency and set it in a parameter. In another parameter, select and set an appropriate option based on a combination of these signals.
I/O Signal Timings The maximum response time after a control signal is turned ON to operate the ROBO Cylinder in a PLC sequence program, until a corresponding response (status) signal is returned to the PLC, is expressed by the formula below: Maximum response time (msec) = Yt + Xt + 3 + command processing time (operation time, etc.) Yt: Master station node transmission delay...

Page 233
(5) Servo ON command (SON) [PLC output signal] Ready (SV) [PLC input signal] When the SON signal is turned ON, the servo will turn on. When the servo turns on, the status indicator LED (refer to 4.4, “DeviceNet Interface”) on the front panel of the controller will illuminate in green.
Page 234
(6) Home return (HOME) [PLC output signal] Home return complete (HEND) [PLC input signal] Home return in progress (GHMS) [PLC input signal] When the HOME signal is turned ON, the HOME command will be processed at the leading (ON) edge of the signal and home-return operation will be performed automatically.
Page 235
(7) Positioning start (CSTR): Used in the position/simple direct mode 1,2 [PLC output signal] The CSTR command is processed at the leading (ON) edge of the signal, upon which the actuator will move to the position set by the target position corresponding to the specified position number or by the target position channel of the PLC.

(12) Zone 1 (ZONE1) [PLC input signal] Zone 2 (ZONE2) [PLC input signal] Position zone (PZONE) [PLC input signal] Each signal turns ON when the current position of the actuator is inside the specified zone, and turns OFF when the current position is outside the zone. [1] Zone 1, zone 2 Each zone is set by user parameters.
Page 238
(13) +Jog (JOG+) [PLC output signal] -Jog (JOG-) [PLC output signal] These signals are used as starting commands for jog operation or inch operation. If a + command is issued, the actuator will operate in the direction opposite home. When a – command is issued, the actuator will operate in the direction of home.
Page 239
(14) Jog-speed/inch-distance switching (JVEL) [PLC output signal] This signal is used to switch between the jog speed parameter when jog operation is selected, and the inch distance parameter when inch operation is selected. JVEL signal Jog operation: JISL = OFF Inch operation: JISL = ON Parameter No.
Page 240
(16) Teaching command (MODE) [PLC output signal] Teaching mode signal (MODES) [PLC input signal] When the MODE signal is turned ON, the actuator mode will switch from normal operation to teaching. Upon switching to the teaching mode, the controller of each axis will turn the MODES signal ON. Program the PLC so that teaching operation will be performed after the MODES signal turns ON.
Page 241
(19) Operation mode (RMOD) [PLC output signal] Operation mode status (RMDS) [PLC input signal] The operation mode is selected as shown below based on the RMOD signal and the MODE switch on the front panel of the controller. Whether the current mode is AUTO or MANU can be checked using the RMDS signal. The combinations of RMOD signal and MODE switch settings and the corresponding operation modes are shown below.
Page 242
(23) Load missed in push motion (PSFL) [PLC input signal] This signal turns ON when the actuator has not contacted the load in push-motion operation after having moved the distance set by the “Positioning band” field in the position table stored in the controller or by the positioning band channel of the PLC.
Page 243
(26) Load output judgment (LOAD) [PLC input signal] This signal is effective only during push-motion operation. To use the LOAD signal in a press-fit application, the controller must know whether the specified load threshold has been reached during push-motion operation. The load threshold and check range are set by the PLC, and the LOAD signal will turn ON when the command torque (motor current) exceeds the threshold inside the check range.
Page 244
(27) Torque level (TRQS) [PLC input signal] This signal is effective only during push-motion operation. If the motor current reaches the load threshold during push-motion operation (= while the actuator is moving within the positioning band), the TRQS signal will turn ON. Since the level of current is monitored, the ON/OFF status of this signal will also change when the current changes.
Page 245
(29) Vibration Damping Control Mode Selection 0, 1 (NTC0, NTC1) [PLC Output Signal] The vibration damping control function suppresses the load vibration induced by IAI’s actuator. Measure the vibration frequency and set it in a parameter. In another parameter, select and set an appropriate option based on a combination of these signals.

Select a desired mode before issuing an actuator move command. MOD1 MOD0 Pattern name Remarks Trapezoid pattern Factory setting S-motion Primary delay filter Not available.
Page 247
(31) Standstill Mode Selection (ASO0, ASO1) [PLC Output Signal] Select the stop mode to be applied while the actuator is standing by to move to the next position after completing a positioning. If the actuator remains standstill for a long time, the servo is turned off automatically to lower the power consumption.

Signal input is recognized Calibration time continuously for 20 ms Turn the CLBR OFF after confirming that the CEND has turned ON. The CEND turns ON when the calibration has completed successfully. If the CLBR is OFF, the CEND remains OFF. *1 If the CLBR is turned OFF during this period, the signal is not recognized and therefore calibration is not performed.
I/O Signal Timings The maximum response time after a given control signal is turned ON to operate the ROBO Cylinder using the PLC’s sequence program, until a response (status) signal is turned, is expressed by the formula below: Maximum response time (msec) = Yt + Xt + 2 + Command processing time (operation time, etc.) Yt: Master station slave station transmission delay time Field network transmission delay time...
