Fuji Electric RYS201S3-VVS - Changeover of Response Rate; Auto-Tuning Related Parameters; Speed Feedback Filter

MHT258a (Engl.)6-7
The following 3 basic para. can be automatically adjusted according to the setting value of the operating speed response (basic para. 33).
Basic parameter 37 to 39
Para. Name Setting range Initial value Change
37 Torque filter time constant 0.00 to 20.00 [ms] (in 0.01s steps) 0.30 Always
38 Speed regulator integration time 1 to 1000 [ms] (in 1ms steps) 20 Always
39 Position controller gain 1 to 1000 (in increments of 1) 50 Always
Basic para. 37 to 39 can be automatically rewritten only when the “auto” has been selected in the tuning method (basic para. 31).
Remark : The values of basic para. 37 to 39 are rewritten once the operating speed response (basic para. 33) is changed.
Basic para. 37 to 39 can also be set manually after these have been changed by the amplifier. Usually amplifier set value is
used.
Auto-tuning related parameters
■ Changeover of response rate
The motor response rate can be changed over between when the motor is rotating and when the motor is stopping. This is effective to
reduce the noise when stopping and suppress the resonance with the mechanical equipment system.
Basic parameter 34 to 36
Para. Name Setting range Initial value Change
34 Speed response at stoppage 10 to 1000 [Hz] (in 1Hz steps) 100 Always
35 Stoppage detection width 5 to 100 [r/min] (in increments of 1) 20 Always
36 Stoppage judgment time 0.0 to 1.00s (in 0.01s steps) 0.0 Always
Remarks : “Operating speed response” and “speed response at stoppage” should be changed after the speed has been lower than the
stoppage detection width (basic para. 35) and the stoppage judgment time (basic para. 36) has elapsed. This can prevent the
motor shaft from starting rotating after the motor has stopped if the setting of “speed response at stoppage” is low. Set an
appropriate time for the stoppage judgment time as its initial value is 0.0s.
■ Speed feedback filter
When you use 16 bit serial encoder in GYC or GYS series, do not change the setting of the speed feedback filter.
Basic parameter. 42
Para. Name Setting range Initial value Change
42 Speed feedback filter 0: OFF 1: ON 0 Always
