5.4 Parameter description in detail
Time-constant of exponential form
P040
filter for position command
Range
0～1000
Default
value
0
Unit Usage
ms
P
z Carries on the smooth filter to the command pulse and has the exponential form acceleration/deceleration.
The filter cannot lose the input pulse, but can delay the command pulse. When the setting value is zero, the
filter does not have any effect.
z This filter uses in some cases:
1. The host controller has no acceleration/deceleration function;
2. The electronic gear ratio is quite big (N/M>10);
3. The command frequency is lower;
4. When the servomotor is in motion appears step-by-steps or unstable phenomenon.
Acceleration time of speed
P060
command
Range
0～30000

Unit Usage

S
z Set the acceleration time for the servomotor from the zero speed up to rated speed.
z If the command speed is lower than the rated speed, the rise time also correspondingly reduces.
z Only uses in the speed control mode. It is invalid in position control mode.
z If the servo driver constitutes the position control with host controller, this parameter should be set zero,
otherwise affects the position control performance.
