F1-18: dv3 Detection Selection (CLV/PM)
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets the number of times the drive will detect a dv3 situation before triggering a dv3 fault. The drive detects a dv3 condition
when the torque reference and speed reference are in opposite directions while the difference between the actual motor speed
and the speed reference is greater than 30%. Setting F1-18 to 0 disables dv3 detection.
No. Parameter Name Option Port Setting Range Default
F1-18 dv3 Detection Selection CN5-B, CN5-C 0 to 10 10
Note: A common cause for a dv3 fault is the incorrect setting of E5-11. Make sure to enter the correct Z Pulse offset to E5-11.
n
F1-19: dv4 Detection Selection (CLV/PM)
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets the number of pulses necessary to trigger a dv4 fault when there is a motor speed deviation opposite to the frequency
reference. Setting F1-19 to 0 disables dv4 detection.
No. Parameter Name Option Port Setting Range Default
F1-19 dv4 Detection Selection CN5-B, CN5-C 0 to 5000 128
Note: 1. A common cause for a dv4 fault is the incorrect setting of E5-11. Make sure to enter the correct Z-pulse offset to E5-11.
2. Set F1-19 to 0 for applications where the direction of the load is the opposite of the speed reference.
n
F1-20, F1-36: PG Option Card Disconnect Detection
Sets whether the drive detects a fault when a PG-X3 card is disconnected.
No. Parameter Name Option Port Setting Range Default

F1-21, F1-37: PG 1, PG 2 Signal Selection (V/f w/PG only)
Determines whether the signal to the PG option card is single-channel or two-channel.
No. Parameter Name Option Port Setting Range Default
F1-21 PG 1 Signal Selection CN5-C 0, 1 0
F1-37 PG 2 Signal Selection CN5-B 0, 1 0
