Additional Tuning Options
C1 – 03 Acceleration Time 2
C1 – 04 Deceleration Time 2
These parameters are set to provide different ramp times when one of the input terminals (3 through 8) is pro-
grammed to "Multi-accel/decel 1" (setting "7"). See parameters H1-01 through H1-06. This allows the user to pro-
gram different acceleration and deceleration rates for various conditions.
Minimum Maximum Description
0000.0 6000.0
C1 – 09 Fast Stop Time
This parameter is set to provide a ramp time when one of the input terminals (3 through 8) is programmed to "Fast
Stop Command" (setting "15"). See parameters H1-01 through H1-06. This allows the user to program a rapid
deceleration rates for a quicker than normal stop.
Minimum Maximum Description
0000.0 6000.0
NOTE: Attempting to stop the motor faster than it will coast to a stop by itself (with power off) may require the addi-
tion of a resistor-braking unit.
ASR Tuning Options
The Automatic Speed Regulator (ASR) allows the user to adjust for optimum performance during changes in motor
speed or load.
Speed Reference
Speed Feedback
C5 – 01 ASR Proportional Gain 1
C5 – 03 ASR Proportional Gain 2
The Proportional Gain adjusts the speed in response to a speed deviation, and softens the effects of load changes.
Response becomes more noticeable as the gain is increased. High levels may cause instability.
ASR Proportional Gain 2 is activated by programming one of the input terminals (3 through 8) to "ASR Gain Switch
(setting "77") and closing a contact to it.
