Autotuning Constants: C - YASKAWA FSDrive-MV1S Instructions Manual

Autotuning Constants: C

The following settings are made with the autotuning constants (C constants): Acceleration/deceleration times,
s-curve characteristics, slip compensation, torque compensation, and speed control.
Acceleration/Deceleration: C1
User constants for acceleration and deceleration times are shown in the following table.

Description
Range
Sets the acceleration time to
accelerate from 0 to the maxi-
mum output frequency, in 1-
second units.
Sets the deceleration time to
decelerate from the maximum
output frequency to 0, in 1-sec-
ond units.
The acceleration time when the
multi-function input "accel/
decel time 1" is set to on.
The deceleration time when the
multi-function input "accel/
decel time 1" is set to on.
The acceleration time when the
multi-function input "accel/
decel time 2" is set to on. 0.0 to
6000.0
The deceleration time when the
multi-function input "accel/
decel time 2" is set to on.
The acceleration time when the
multi-function input "accel/
decel time 1" and "accel/decel
time 2" are set to on.
The deceleration time when the
multi-function input "accel/
decel time 1" and "accel/decel
time 2" are set to on.
The deceleration time when the
multi-function input "Emer-
gency (fast) stop" is set to on.
This function can be used as a
stopping method when a fault
has been detected.
Sets the frequency for auto-
matic acceleration/deceleration
switching.
Below set frequency: Accel/
decel time 4 0.0 to
Above set frequency: Accel/ 100.00
decel time 1
The multi-function input
"accel/decel time 1" or "accel/
decel time 2" take priority.
