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 suf fi-
cient output current ca -

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.)

Torque
compensa-

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.
