B.2 Parameter Table u C: Tuning C parameters are used to adjust the acceleration and deceleration times, S-curves, slip and torque compensation functions and carrier frequency selections. 172 SIEP C710606 33A OYMC AC Drive – J1000 User Manual No. Name Description Range Def. Mode Addr. Hex Pg. b2-03 DC Injection Braking Time/DC Excitation Time at Start Sets DC Injection Braking time at start. Disabled when set to 0.00 seconds. 0.00 to 10.00 0.00 s O 18B 76 b2-04 DC Injection Braking Time at Stop 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.
0.00 to 10.00 0.50 s O 18C 76 No. Name Description Range Def. Mode Addr. Hex Pg. C1: Acceleration and Deceleration Times Use C1 parameters to configure motor acceleration and deceleration. C1-01 Acceleration Time 1 Sets the time to accelerate from 0 to maximum frequency. 0.0 to 6000.0 10.0 s S 200 77 C1-02 Deceleration Time 1 Sets the time to decelerate from maximum frequency to 0. S 201 77 C1-03 Acceleration Time 2 Sets the time to accelerate from 0 to maximum frequency when Accel/Decel times 2 are selected by a digital input. O 202 77 C1-04 Deceleration Time 2 Sets the time to decelerate from maximum frequency to 0 when Accel/Decel times 2 are selected by a digital input.
O 203 77 C1-09 Fast-Stop Time 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. O 208 77 C2: S-Curve Characteristics Use C2 parameters to configure S-curve operation. C2-01 S-Curve Characteristic at Accel Start The S-curve can be controlled in the four points shown below. Run ON OFF command Output frequency C2-02 C2-03 C2-04 C2-01 Time 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.
0.00 to 10.00 0.20 s O 20B 78 C2-02 S-Curve Characteristic at Accel End 0.00 to 10.00 0.20 s O 20C 78 C2-03 S-Curve Characteristic at Decel Start 0.00 to 10.00 0.20 s O 20D 78 C2-04 S-Curve Characteristic at Decel End 0.00 to 10.00 0.00 s O 20E 78 C3: Slip Compensation Use C3 parameters to configure the slip compensation function. C3-01 Slip Compensation Gain 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. 0.0 to 2.5 0.0 O 20F 78 C3-02 Slip Compensation Primary Delay Time 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. 0 to 10000 2000 ms O 210 78 C4: Torque Compensation Use C4 parameters to configure Torque Compensation function. C4-01 Torque Compensation Gain 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. 0.00 to 2.50 1.00 O 215 78 C6:
Carrier Frequency Use C6 parameters to configure the carrier frequency drive settings. C6-01 Normal/Heavy Duty Selection 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. 0, 1 0 S 223 79
