■ F1-18: dv3 Detection Selection (CLV/PM)
A dv3 situation is detected 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%. Parameter F1-18 sets the number of times
such a situation must occur before a dv3 fault is triggered. Setting F1-18 to 0 disables dv3 detection.
Note: A common cause for a dv3 fault is the incorrect setting of E5-11. Make sure the correct Z pulse offset has been entered to E5-11.
■ F1-19: dv4 Detection Selection (CLV/PM)
A dv4 fault is triggered when there is a motor speed deviation opposite to the frequency reference and larger than the
number of pulses set in F1-19. Setting F1-19 to 0 disables dv4 detection.
Note: 1. A common cause for a dv4 fault is the incorrect setting of E5-11. Make sure the correct Z pulse offset is set to E5-11.
2. Set F1-19 to 0 for applications where the direction of the load is the opposite of the speed reference.
■ F1-20, F1-36: PG Option Card Disconnect Detection
Sets whether the drive detects a fault or not when a PG-X3 card is disconnected.
Setting 0: Disabled
Setting 1: Enabled
■ 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 track or two track.
Setting 0: Single track (A track only)
Setting 1: Two track (tracks A and B)
■ F1-30: PG Option Card Port for Motor 2 Selection
Specifies the drive port for the PG option card used for motor 2. This parameter should be set when switching between
motor 1 and motor 2, where both motors supply a speed feedback signal to the drive. If the same PG card is being used
for feedback signals from both motors, then set F1-30 to 0. If each motor has its own PG card connected to the drive, then
set F1-30 to 1.
Note: The motor 2 selection function cannot be used when PM motor is used.
