Chapter 4: AC Drive Parameters
P6.06 Base Block Speed Search after Fault (oc,ov,bb)
Range/Units (Format: 16-bit binary)
0: Disable
1: Speed search starts with current speed reference
2: Speed search starts with minimum output frequency
Fault includes: Base Block BB, over-current OC, over-voltage OV, short circuit OCC. To restart after
oc, ov, occ, P6.04 cannot be set to 0.
Related parameters: P6.04, P6.05, P6.23
P6.07 Speed Search at Start
Range/Units (Format: 16-bit binary)
0: Disable
1: Speed search from maximum output frequency
2: Speed search from start-up motor frequency
3: Speed search from minimum output frequency
This parameter is used for starting and stopping a motor with a high inertia. A motor with high
inertia will take 2–5 minutes or longer to stop completely. By setting this parameter, the user does
not need to wait for the motor to come to a complete stop before restarting the GS4 drive.
Related parameters: P6.24 (sets the output current)
P6.08 Momentary Power Loss
Range/Units (Format: 16-bit binary)
0: Disable
1: Speed search from last frequency command
2: Speed search from the minimum output frequency
This parameter determines the operation mode when the GS4 drive restarts from a momentary
power loss. The power connected to the drive may power off momentarily due to many reasons.
This function allows the drive to keep running after power comes back on line; won't cause drive
stop.
Setting Explanations:
0: Stop operation after momentary power loss.
1: Operation continues after momentary power loss, speed search starts with the Master
Frequency reference value after drive output frequency, and motor rotator speed is
synchronous. The motor will have a closer characteristic of a lot of inertia and low
resistance. For example, in equipment with a big inertia wheel, the motor will take a long
time to stop. The drive does not need to wait for the wheel to stop in order to start again.
2: Operation continues after momentary power loss, speed search starts with the
minimum output frequency after drive output frequency, and motor rotational speed
is synchronous. The motor will have a closer characteristics of less inertia and more
resistance.
Related parameters: P6.04, P6.05
