Logic Inputs
F-Stop (Fast Stop) has priority over the other operating states. F-Stop forces the Control Output SigU and
SigW signals to “0” volts and monitors the feedback. When the feedback is less than the Zero Speed (CP-
370), the UwndDrvEn (PLC bit 41) and WindDrvEn (PLC bit 51) 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 UwndDrvEn (PLC bit 41) and WindDrvEn (PLC bit 51)automatically resets to “0”. The integral,
trim and feedforward are also set to “0”.
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
