F-Stop (J6 pins 1, 3) Digital Input 0 F-Stop is a momentary input. When it is opened, the CX-1200 commands a zero speed immediately and ignores the specified deceleration rate. However, F-Stop does not hold zero speed or position (drive disabled). As a momentary input, F-Stop is internally latched and does not need to be maintained open by an operator device. F-STOP DI_0 1 Com 3 J6 Figure 15 F-Stop R-Stop (J6 pins 2, 3) Digital Input 1 R-STOP R-Stop is a momentary input.
Run (J6 pins 5, 3) Digital Input 3 RUN When the Run input (J6, pin 6) is momentarily shorted to common, the CX-1200 enters the Run state. As a momentary input, Run is internally latched and does not need to be maintained closed by an operator device. Com 3 DI_3 5 J6 NOTE: Close the R-Stop, H-Stop, and F-Stop inputs prior to entering the Run state. If you are only using one of the Stop inputs, wire short the other Stop inputs to the common or the CX1200 will not enter run.
Keypad Lockout (J6 pins 9, 8) Digital Input 6 When the Keypad Lockout input is closed, the Control Parameters that you have selected to "lock out" are inaccessible from the front keypad. All of the Monitor Parameters remain enabled. Com 8 DI_6 9 ENABLE LOCKOUT J6 Figure 21 Keypad Lockout Spare (J6 pins 10, 8) Digital Input 7 The Spare input is not defined at this time. Com 8 DI_7 10 Spare J6 Figure 22 Spare Block Select A (J7 pins 1,3) Digital Input 8 Block Select A is a maintained input.
Batch Reset (J7 pins 2,3) Digital Input 9 Batch Reset is a momentary input. When it is closed, the CX1200 resets the internal batch counter to zero. The default internal batch counter is "Cntr1 Cnt" (CP-421) a PLC event counter. Batch Reset DI_9 2 Com 3 J7 Figure 24 Batch Reset Re-Learn (J7 pins 4, 3) Digital Input 10 Re-Learn is a momentary input. When it is closed, the CX1200 initiates a Re-Learn process in one of the sync follower modes.
Position Reset (J7 pins 6, 8) Digital Input 12 Position Reset Position Reset is a momentary input. When it is closed, the CX-1200 resets the Lead and Follower position information to zero. DI_12 6 Com 8 J7 Figure 27 Position Reset Sync Disable (J7 pins 7, 8) Digital Input 13 Sync Disable is a maintained input. When it is closed, it disables sync corrections.
Phase Retard (J7 pins 10, 8) Digital Input 15 Phase Retard is a maintained input. When it is closed it increments the CP selected by "Remote Scroll" (CP-400) at the rate set by "Rmt Scroll Rate" (CP-401). As a maintained input, Phase Retard is only active when the operator device is closed.
OUTPUTS NOTE: The installation of this motor control must conform to area and local electrical codes. Refer to page 9 before you begin wiring. Control Output (J3 pins 1, 2) Control Output is an isolated analog output signal that is sent to the motor drive to control the speed of the motor.

LOGIC CONTROL This section addresses the six digital inputs that control the CX-1200's operating state. The six digital inputs ( listed in by priority) are: F-Stop R-Stop H-Stop Run Jog Forward Jog Reverse When the CX-1200 is powered up, it defaults to R-Stop. If either Run or Jog have been hardwired, the CX1200 will operate in either Run or Jog instead of R-Stop. Run is hardwired by shorting Run, R-Stop and FStop to common.
Logic Inputs F-Stop (Fast Stop) has priority over the other operating states. F-Stop forces the CO signal to “0” volts and monitors the feedback. When the feedback is less than the Zero Speed (CP-332), the Drive En (PLC bit 41) resets to “0”. This PLC bit is routed by the PLC program to an output that disables the drive. If the feedback does not reach Zero Speed within 1/2 second, the Drive En (PLC bit 41) automatically resets to “0”.
R-Stop (Ramp Stop) has the second highest operating priority. Use R-Stop to stop the drive with a deceleration ramp. The velocity command is ramped down to “0”. If the loop is “Closed”, the ramp is executed with velocity loop control (with feedforward, using Kff ). If the loop is “Open”, the ramp is executed with feedforward only (using Kff ). The deceleration rate for the ramp is determined by Dcl Tm RStp (CP-310) and Ref StopRmp (CP-210) or by the Dcl Rt RStp (CP-311).
H-Stop (Stop and Hold) has the third highest operating priority. Use H-Stop to stop the drive with a deceleration ramp. The velocity command is ramped down to “0”. If the loop is “Closed”, the ramp is executed with velocity loop control (with feedforward, using Kff ). If the loop is “Open”, the ramp will be executed with feedforward only (using Kff). The deceleration rate for the ramp is determined by Dcl Tm HStp (CP-312) and Ref StopRmp (CP-210) or by the Dcl Rt RStp (CP-311).
Run has the fourth highest operating priority. Run is the primary operating state. RUN Mode (CP-202) determines the mode of operation for Run, using either the master mode, the follower mode, the direct mode. The corresponding setpoint for the selected mode determines the operating speed. RUN Mode (CP-202) determines the control loop that is used during Run. At times, the selected RUN Mode is overridden. The direct mode will only operate in an open loop. The master mode will “Run” in velocity loop.
Jog Forward has the fifth highest operating priority. Use Jog Forward to “Jog” the drive Forward at the rate indicated in Jog SP (CP-240). The acceleration and deceleration ramps are dictated by Acl Tm Jog (CP-241), Dcl Tm Jog (CP-243) and Jog SP (CP-240). After the Jog Forward input is deactivated and the ramped reference has reached “0”, the CX-1200 automatically reverts to the R-Stop operating state.
Jog Reverse has sixth (the least) operating priority. Use Jog Reverse to “Jog” the drive Forward at the rate indicated in Jog SP (CP-240). The acceleration and deceleration ramps are dictated by Acl Tm Jog (CP-241), Dcl Tm Jog (CP-243) and Jog SP (CP-240). After the Jog Reverse input is deactivated and the ramped reference has reached “0”, the CX-1200 automatically reverts to the R-Stop operating state.
