Revision August 2008, 03VE, SW V2.04 4-111
07-10 Base Block Speed Search
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 0
Settings 0 Stop operation
1 Speed search starts with last frequency command
2 Speed search starts with minimum output frequency
This parameter determines the AC motor drive restart method after External Base Block is
enabled.
In PG control mode, the AC motor drive will execute the speed search function automatically
by the PG speed when this setting isn’t set to 0.
07-11 Auto Restart After Fault Unit: 1
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 0
Settings 0 to 10
Only after an over-current OC or over-voltage OV fault occurs, the AC motor drive can be
reset/restarted automatically up to 10 times.
Setting this parameter to 0 will disable the reset/restart operation after any fault has occurred.
When enabled, the AC motor drive will restart with speed search, which starts at the frequency
before the fault. To set the waiting time before restart after a fault, please set Pr. 07-08 Base
Block Time for Speed Search.
07-12 Speed Search during Start-up
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 0
Settings 0 Disable
1 Speed search from maximum frequency
2 Speed search from start-up frequency
3 Speed search from minimum frequency
This parameter is used for starting and stopping a motor with high inertia. A motor with high
inertia will take a long time 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 AC motor drive. If a
PG card and encoder is used on the drive and motor, then the speed search will start from the
speed that is detected by the encoder and accelerate quickly to the commanded frequency.
The output current is set by the Pr.07-09.
