Parameter # 12
Parameter Name Acceleration time 2
Factory Setting d010.0 Sec
Units 0.1 Sec
Parameter value d000.1 - d600.0 Sec
This parameter can be programmed while the drive is running.
This parameter determines the time required for the AC drive to ramp from 0 Hz to
the Maximum operating frequency (Pr.03). The rate is linear unless S Curve is
“Enabled.” Acceleration time 1 is the default. A Multi-Function Input Terminal can
be programmed to select Acceleration time 1 or Acceleration time 2. See
parameters 39, 40, and 41.
Parameter # 13
Parameter Name Deceleration time 2
Factory Setting d010.0 Sec
Units 0.1 Sec
Parameter value d000.1 - d600.0 Sec
This parameter can be programmed while the drive is running.
This parameter determines the time for the AC drive to decelerate from the
Maximum operating frequency (Pr.03) down to 0 Hz. The rate is linear unless S
Curve is “Enabled.” Deceleration time 1 is the default. A Multi-Function Input
Terminal can be programmed to select Deceleration time 1 or Deceleration time 2.
See parameters 39, 40, and 41.
Pr.14
Jog Accel / Decel Time
Parameter # 14
Parameter Name Jog Accel / Decel time select
Factory Setting d010.0 Sec
Units 0.1 Sec
Parameter value d000.1 - d600.0 Sec
This parameter can be programmed while the drive is running.
This parameter determines the time required for the AC Drive to ramp from 0 Hz to the
Jog frequency and the time required to ramp from the Jog frequency to 0 Hz.
This parameter must accompany with parameter P111 deceleration S curve. In order to
get the different results of S curves, just setting the parameter P111 to meet the
requirement.
