Programming Reference 4-25
In V/Hz regulation, this parameter specifies the time in which the motor ramps from
zero speed to Maximum Speed (P.004).
In vector regulation, this parameter specifies the time in which the motor ramps from
zero speed to Motor Top Speed (U.017).
The time it takes the motor to make any speed increase is directly proportional to the
value in this parameter. This parameter does not apply if JOG is selected.
In V/Hz regulation, this parameter specifies the time in which motor speed ramps from
Maximum Speed (P.004) to zero speed.
In vector regulation, this parameter specifies the time in which motor speed ramps
from Motor Top Speed (U.017) to zero speed.
The time it takes the motor to make any speed decrease (except a coast-to-rest stop)
is directly proportional to the value in this parameter.
This parameter does not apply if JOG is selected.
P.017 Accel Time 2 (RAMP 2)
This parameter sets
the acceleration time
when a second ramp
selection is
configured as a
digital input.
When the RAMP 2
acceleration time
digital input is
asserted, the
RAMP 2 deceleration
time also takes effect.
Parameter Range: 1.0 to 999.9 seconds (V/Hz)
0.1 to 999.9 seconds (vector)
Default Setting: 20.0
Parameter Type: Tunable

P.018 Decel Time 2 (RAMP 2)
This parameter
specifies the
deceleration time
when a second ramp
selection is
configured as a
digital input.
When the RAMP 2
deceleration time
digital input is
asserted, the RAMP
2 acceleration time
also takes effect.
Parameter Range: 1.0 to 999.9 seconds (V/Hz)
0.1 to 999.9 seconds (vector)
Default Setting: 20.0
