NETWORK VARIABLES
6.8.9 Deceleration time (network input config SNVT_time_sec
nciRampDownTm)
You can set the deceleration time taken for the motor to reach 0Hz from the set frequency (1 to 400Hz) of
Pr. 20 Acceleration/deceleration reference frequency.
* The setting range changes according to the Pr. 21 Acceleration/deceleration time increments setting. The value 0.1 times greater than
the setting value is written to the inverter when Pr. 21 = 1. When the Pr. 21 setting has been changed, set the deceleration time again.
(Example)
When Pr. 21 = "0", setting "5.0s" for deceleration time and "1" in Pr. 21 automatically changes the deceleration time setting to "0.5s".
