PC01 Acceleration time constant
Used to set the acceleration time required to reach
the rated speed from 0 r/min in response to the
analog speed command and internal speed
commands 1 to 7.

Parameter
No.PC01 setting
For example for the servo motor of 3000 r/min rated
speed, set 3000 (3 s) to increase speed from 0 r/min
to 1000 r/min in 1 second.
PC02 Deceleration time constant
Used to set the deceleration time required to reach
0 r/min from the rated speed in response to the
analog speed command and internal speed
commands 1 to 7.
If the preset speed command is
lower than the rated speed,
acceleration/deceleration time
will be shorter.

value
0.00 PB36 Vibration suppression control 1 - Resonance
frequency damping after gain switching
Set a damping of the resonance frequency for
vibration suppression control 1 when the gain
switching is enabled.
This parameter will be enabled only when the
following conditions are fulfilled.
"Gain adjustment mode selection" in [Pr. PA08] is
"Manual mode (_ _ _ 3)".
"Vibration suppression control 1 tuning mode
selection" in [Pr. PB02] is "Manual setting (_ _ _
2)".
"Gain switching selection" in [Pr. PB26] is "Input
device (gain switching (CDP)) (_ _ _ 1)".
Switching during driving may cause a shock. Be
sure to switch them after the servo motor stops.
Setting range: 0.00 to 0.30

Acceleration time constant
Set the acceleration time required to reach the rated
speed from 0 r/min for VC (Analog speed command)
and [Pr. PC05 Internal speed command 1] to [Pr.
PC11 Internal speed command 7].
