Description
All Modes
Used to suppress speed oscillations that occur with an unloaded motor and that have the same
frequency as the output frequency.
All Modes
0: Mode 0
1: Mode 1
All Modes
Enables or disables the Current Monitoring function.
0: Disabled
1: Enabled
All Modes
Sets the current monitoring level as a percentage of the drive's rated current. Sets the level of
current used for L8-89 and H2- = 5C.
Description
All Modes
0: Method 1
1: Method 2
Description
V/f OLV
Sets the internal speed feedback detection control gain in the automatic frequency regulator
(AFR).
If hunting occurs, increase the set value. If response is low, decrease the set value.
V/f OLV
Sets the time constant used for speed feedback detection control (AFR).
V/f OLV
Sets the AFR time constant to be used during regen.
Description
V/f OLV
0: Disabled
1: Enabled
V/f OLV
Sets the time required to accelerate the motor at 100% torque from 0 to the nominal speed.
V/f OLV
Sets the ratio between motor and load inertia. Lower this setting if overshoot occurs at the end
of acceleration.
V/f OLV
0: Disabled
1: Enabled
