C: Tuning

C parameters are used to adjust the acceleration and deceleration times, S-curves, slip and torque compensation functions and
carrier frequency selections.

Description
Sets the phase order for drive output terminals U/T1, V/T2 and W/
T3.
0 : Standard
1 : Switch phase order
Determines the operation when a Run command is active at power
up of the drive.
0: Run command not issued, needs to be cycled
1: Run command issued, motor operation start
b2: DC Injection Braking
Use b2 parameters to configure DC Injection Braking operation
Sets the DC Injection Braking current as a percentage of the drive
rated current.
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.
C3: Slip Compensation
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.
