Constant C3-03 sets the slip compensation limit as a percentage
of motor rated slip (E2-02), with the
motor rated slip taken as 100%.
If the speed is lower than the target value and does not
change even when the slip compensation gainis adjusted,
it is possible that the slip compensation limit has been reached.
Raise the limit and thencheck again. Make sure, however,
that the value of the sum of the reference frequency and
the slip compensationlimit does not exceed the speed
capacity of the machinery.

The amount of regeneration is momentarily increased when
this function is used, so some control option(e.g., Braking
resistor, Braking Resistor Unit, Braking Unit) may be
required.
Flux is calculated based on theoutput frequency after
compensation pensation.
Flux is calculated based on the
output frequency before compensation.

Limited output voltage operation
Description of choice Description of choice
If the limited output voltage operation is disabled and output
voltage becomes saturated, the outputcurrent does not chang
- e. However, torque control precision is no longer possible.
Enable limited output voltage operation if precise torque
control is required.
If the limited output voltage operation is enabled, the magneti
- c flux current of the motor is automaticallycontrolled, and the
output voltage command itself is limited, which maintains pr
- ecise torque control.Check the Inverter current margins as
the output current will be maximum 10% higher (with a rated
load) than when limited output voltage operation is disabled
C3-06 does not need to be changed if the Unit is used only at medium
or low speeds, orhen the power supply voltage is10% or more
higher than the rated voltage for the motor, when torque control
precision in the high-speed region is not required.When the power
supply voltage is too low for the rated motor voltage, precise torque
controlwill not be maintained even if limited output voltage operation
is enabled.

Function Function
Description of choice Description of choice
Sets torque compensation gain as a ratio.
This constant can be changed during operation, but normally
no adjustments are required. Make adjustmentsin the following
cases under the V/f control mode:
If the wiring distance between the Inverter and the motor is long, raise the
If the motor capacity is less than the Inverter capacity (the maximum
application motor capacity),raise the setting.
If the motor generates excessive oscillation, lower the setting.
SettingRange SettingRange
Adjust the output current range atminimum speed rotation
so that it does not exceed the Inverter ratedoutput current.
Do not alter the torquecompensationgain when in open-loop
vectorcontrol mode.
The torque compensation delaytime is set in ms units.
* When the control method is switched, the factory setting changes
as follows:V/f control, V/f with PG : 200 [1000 ms for inverters
of 30 kW or larger (200 V class), orinverters of 55 kW or larger
(400 V class)]; open-loop vector : 20D The torque compensation
time constant does not normally need to be adjusted, but make
adjustmentsin the following cases:
• If the motor generates excessive oscillation, raise the setting.
• If motor responsiveness is low, lower the setting.

Function Function
Sets the start torque constant in ms units.
When this function is used, set the starting torque value to the
friction load value for ordinary machinery,and to the load for
cranes and other lifting devices. Friction load: Set the friction
load for both C4-03 and C4-04.Lifting devices: Set the load for
the motor side only (hoist). Do not use this function for lifting
deviceswith counterweights as a shock will be generated if
there is a regenerative load.D Compensation canbe set only
for the motoring side, for both the forward and reverse directions.
It cannotbe set for the regenerative side.
