CP-371 Max Fb Alm
Maximum Feedback Alarm (CP-371) signals an over-speed condition. When the magnitude of the Fb EU/Tm (MP-39) is
greater than or equal to Max Fb Alm (CP-371), then the MaxFb Spd bit (55) in the PLC is set to “1”. You can output this
alarm for indication or action, or you can use the alarm logically in the PLC.
Minimum Value: 0 Maximum Value: 9999999
Default Value: 2000 Units: EU/Tm
CP-372 Max Acl/Dcl
When either the feedback acceleration or the deceleration is greater than or equal to Maximum Accel/Decel (CP-372),
then the MaxAclDcl bit (56) in the PLC is set to “1” . You can output this alarm for indication or action, or you can use
the alarm logically in the PLC.
Minimum Value: 0 Maximum Value: 9999999
Default Value: 2000 Units: EU/Sec 2
CP-373 NO Resp Time
When the CO_Sig output signal is greater than 1/16 CO Max Volts (CP-271) and the Fb EU/Tm (MP-06) is less than Zero
Speed (CP-332) for longer than the No Response Time (CP-373), then the DrvNoRsp bit (57) is set to “1”. If this
scenario occurs, it is generally an indication that the feedback has been lost. It can also indicate that the drive is not
enabled (or faulted out), that the CO_Sig output signal is not getting to the drive or that there may be a physical
obstruction preventing motion.
Minimum Value: 0.010 Maximum Value: 600
Default Value: 1.000 Units: Seconds
CP-374 Posn Alarm
Position Alarm (CP-374) sets a threshold for the magnitude of position error above which the Position Alarm PLC bit is
set = 1. In other words...if the magnitude of PosErr (CP-33) is greater than or equal to the value set for Posn Alarm (CP-
374), then the Position Alarm PLC bit (65) will be set.
Minimum Value: 0.001 Maximum Value: 9999999
Default Value: 999999 Units: EU/Tm
