Description
Sets DC Injection Braking time at start. Disabled when set to 0.00
seconds.
Sets DC Injection Braking time at stop.
When b1-03 = 0, this parameter sets the amount of DC Injection
time applied to the motor at the end of the decel ramp. Disabled
when set to 0.00.
Description
C1: Acceleration and Deceleration Times
Use C1 parameters to configure motor acceleration and deceleration.
Sets the time to accelerate from 0 to maximum frequency.
Sets the time to decelerate from maximum frequency to 0.
Sets the time to accelerate from 0 to maximum frequency when
Accel/Decel times 2 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0 when
Accel/Decel times 2 are selected by a digital input.
Sets the time to decelerate from maximum frequency to 0 for the
multi-function input fast-stop function.
Note: This parameter is also used by selecting "Fast-Stop" as a Stop
Method when a fault is detected.
C2: S-Curve Characteristics
Use C2 parameters to configure S-curve operation.
The S-curve can be controlled in the four points shown below.

S-curve is used to further soften the starting and stopping ramp. The
longer the S-curve time, the softer the starting and stopping ramp.
Use C3 parameters to configure the slip compensation function.
Sets the slip compensation gain. Decides for what amount the output
frequency is boosted in order to compensate the slip.
Note: Adjustment is not normally required.
Adjusts the slip compensation function delay time.
Decrease the setting when the slip compensation response is too
slow, increase it when the speed is not stable.
Use C4 parameters to configure Torque Compensation function.
Sets the gain for the automatic torque (voltage) boost function and
helps to produce better starting torque.
Increase this setting when using a long motor cable or when the
motor is significantly smaller than the drive capacity.
Decrease this setting when motor oscillation occurs. Set the value
so that the current at low speed does not exceeds the drive rated
current.
Use C6 parameters to configure the carrier frequency drive settings.
Selects the load rating for the drive.
0: Heavy Duty (HD) for constant torque applications.
1: Normal Duty (ND) for variable torque applications.
This setting affects the Rated output current and overload tolerance
of the drive.
