Drive Configuration
Accel/Decel Time
You can configure the drive’s acceleration time and deceleration time.
Acceleration Time
P535[Accel Time 1] and P536 [Accel Time 2] set the acceleration rate for all
speed changes. Defined as the time to accelerate from 0 to motor nameplate
frequency P27 [Motor NP Hertz] or to motor nameplate rated speed P28
[Motor NP RPM]. The setting of Hertz or RPM is programmed in P300 [Speed
Units]. Selection between Acceleration Time 1 and Acceleration Time 2 is
controlled by a digital input function (see Digin Functions in the PowerFlex 750-
Series Programming Manual, publication
) or by Logic Command
(sent over a communication network or DeviceLogix™ software).
Adjustment range is 0.00 to 3600.00 seconds.
Deceleration Time
P537 [Decel Time 1] and P538 [Decel Time 2] set the deceleration rate for all
speed changes. Defined as the time to decelerate from motor nameplate
frequency P27 [Motor NP Hertz] or from motor nameplate rated speed P28
[Motor NP RPM] to 0. The setting of Hertz or RPM is programmed in P300
[Speed Units]. Selection between Deceleration Time 1 and Deceleration Time 2
is controlled by a digital input function (see Digin Functions in the PowerFlex
750-Series Programming Manual, publication
) or by Logic
Command (sent over a communication network or DeviceLogix software).
Adjustment range is 0.00 to 3600.00 seconds.
