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-270), 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”. The
integral, trim and feedforward are also set to “0” and the loop is set to Open Loop (OL).
To activate F–Stop:
• Activate High (Open), Level Sensitive, Latched
• Wire to F-Stop interconnect
• Use momentary contact - does not need to be maintained to remain active
