6.2 I/O Signal Allocations6.2.1 Input Signal Allocations6-36 Settings6.2 I/O Signal AllocationsFunctions are allocated to the pins on the I/O signal connector (CN1) in advance. You canchange the allocations and the polarity for some of the connector pins. Function allocationsand polarity settings are made with parameters.This section describes the I/O signal allocations.6.2.1 Input Signal AllocationsChanging Input Signal Allocations Input Signals That Can Be Allocated to CN1-40 to CN1-46The input signals that you can allocate to the pins on the I/O signal connector (CN1) and therelated parameters are given in the following table.• If you change the polarity of the /S-ON (SERVO ON Input) signal from the default setting, youwill not be able to turn OFF the main circuit power supply to the Servomotor if signal lines breakor other problems occur. If you change the polarity of this signal, verify operation and makesure that no safety problems will exist.• If you allocate two or more signals to the same input circuit, a logical OR of the inputs will beused and all of the allocated signals will operate accordingly. This may result in unexpectedoperation.Input Signal Input Signal Name Parameter/S-ON Servo ON Pn50A = n.X/P-CON Proportional Control Pn50A = n.XP-OT Forward Drive Prohibit Pn50A = n.XN-OT Reverse Drive Prohibit Pn50B = n.X/ARM-RST Alarm Reset Pn50B = n.X/P-CL Forward External Torque Limit Pn50B = n.X/N-CL Reverse External Torque Limit Pn50B = n.X/SPD-D Motor Direction Pn50C = n.X/SPD-A Internal Set Speed Selection Pn50C = n.X/SPD-B Internal Set Speed Selection Pn50C = n.X/C-SEL Control Selection Pn50C = n.X/ZCLAMP Zero Camping Pn50D = n.X/INHIBIT Reference Pulse Inhibit Pn50D = n.X/G-SEL Gain Selection Pn50D = n.X/P-DET Polarity Detection Pn50D = n.XSEN Absolute Data Request Pn515 = n.X/PSEL Reference Pulse Input MultiplicationSwitch Pn515 = n.XFSTP Forced Stop Pn516 = n.X/MODE 0/1 Mode Switch Pn630 = n.X/START-STOP Program Table Operation Start-Stop Pn630 = n.X/HOME Homing Pn630 = n.X/PGMRES Program Table Operation Reset Pn630 = n.X/SEL0 Program Step Selection Input 0 Pn631 = n.X/SEL1 Program Step Selection Input 1 Pn631 = n.X/SEL2 Program Step Selection Input 2 Pn631 = n.X/SEL3 Program Step Selection Input 3 Pn631 = n.XContinued on next page.Important
