Skip Speed Band
Sets the bandwidth around a skip speed. [Skip Speed Band] is split, applying 1/2 above
and 1/2 below the skip speed. The same bandwidth applies to all skip speeds. Parameter
is disabled if set to 0.

Accel Time 1

Acceleration Time n
Sets the acceleration rate for all speed changes. Defined as the time to accelerate from 0
to P27 [Motor NP Hertz] or P28 [Motor NP RPM], according to the setting in P300 [Speed
Units]. Selection between Acceleration Time 1 and Acceleration Time 2 is controlled by a
digital input function (see Digin Functions) or by Logic Command (sent over a
communication network or DeviceLogix).

Deceleration Time n
Sets the deceleration rate for all speed changes. Defined as the time to decelerate from
P27 [Motor NP Hertz] or P28 [Motor NP RPM] to 0, according to the setting in P300
[Speed Units]. Selection between Deceleration Time 1 and Deceleration Time 2 is
controlled by a digital input function (see Digin Functions) or by Logic Command (sent
over a communication network or DeviceLogix). Some stop modes (see P370 and P371)
will cause the programmed decel time to be ignored during a stop command.
