C3-03: Slip Comp Limit
No.
(Hex.)
Name
Description
Default
(Range)
C3-03
(0211)
Slip Comp Limit
Sets the upper limit for the slip compensation function as a percentage of the motor rated slip.
200%
(0 - 250%)
If you increase the value of
C3-01 [Slip Comp Gain]
and the motor speed is slow, use this parameter. The drive
uses this parameter when the slip is at the upper limit of slip compensation. Make sure that you measure the motor
speed when you increase this parameter value. Set this parameter to make the frequency reference and the slip
compensation limit less than the permitted range of the machine.
The slip compensation limit is constant in the constant torque range (frequency reference ≤
E1-06 [Base
Frequency]
). In the constant output range where the frequency reference >
E1-06
, the slip compensation limit
increases with the
C3-03
value and the output frequency as shown.

C3-04
(0212)
Slip Comp@Regen
Sets the slip compensation function during regenerative operation.
0
(0 - 2)
If you apply a regenerative load when slip compensation function during regeneration is active, the quantity of
regeneration can increase immediately. In this condition, it is necessary to use a dynamic braking option (braking
resistor or braking resistor unit).
0 : Disabled
The drive does not provide slip compensation during regeneration.
The load and operation status (regenerative operation) can cause the motor speed to be higher or lower than the
frequency reference.
1 : Enable>6 Hz
Slip compensation function is enabled during regeneration. Slip compensation is disabled at output frequencies of
6 Hz or less.
2 : Enable>C3-15
The drive uses
E2-02 [Mot Rated Slip]
to automatically calculate the frequency range where it will disable slip
compensation function during regenerative operation.
Slip compensation is enabled at frequencies as low as 2 Hz.

C3-05: Vout Limit Selection
No.
(Hex.)
Name
Description
Default
(Range)
C3-05
(0213)
Vout Limit Selection
Sets the automatic reduction of motor magnetic flux when the output voltage is saturated.
0
(0, 1)
The drive will decrease flux and increase current to compensate torque when voltage is saturated. Make sure that
the drive has sufficient output current capacity before you enable this parameter. When this parameter =
1
[Enabled]
, the output current will increase by 10% at a maximum (at rated load) before it is enabled.
Enable this parameter to increase speed precision when you move heavy loads at high speeds in these conditions:
•
Power supply voltage is low
•
Motor rated voltage is high
