tion
Selects the output voltage limit
function so that the voltage
calculation in open-loop vector
control does not become
saturated.
0:
Disabled. (Output voltage
saturation is not limited. Slip
compensation is disabled.)
1:
Enabled. (Output voltage
saturation is suppressed.
Speed accuracy is not
reduced.)

Note: Be sure that there is suffi-
cient output current ca-
pacity in the inverter be-
cause the output current
is about 10% higher when
this function is enabled.
Note: The speed accuracy may
be reduced when the in-
put voltage is very low.
Note When the control mode is changed, the Inverter reverts to default settings. (The open loop vector
control default settings are given above.)

Sets torque compensation gain
as a ratio.
Note: Usually setting is not nec-
essary.
Adjust in the following cir-
cumstances:
When the cable is long;
increase the set value.
When the motor capacity
is smaller than the capac-
ity of the Inverter (Max.
applicable motor capac-
ity), increase the set val-

When the motor is vibrat-

When adjusting the gain, be
sure that the output current at
low speeds does not exceed
100% of the Inverter’s rated
output current.
Note: Do not change the torque
compensation gain when
using open-loop vector
control.
