Major Features
Motor Speed Ramp
The MSC-3 has a programmable Ramp with adjustable acceleration, deceleration and S-curve rates.
Individual settings are provided for the linear and curved portions of the ramp

Ramp time with S time set to 0.01
Ramp time with S time set to a value greater than zero
The motor accelerates at a rate of B03 MOTOR Hz / C030 ACCEL TIME and decelerates at a rate of
B03 MOTOR Hz / C031 DECEL TIME. Each of these rates is applied over the C032 S TIME interval to
create the S-curve in the diagram above.
CAUTION
A separate ramp setting is used during Essential Services Override (ESO) operation.
See C034 ESO RAMP for details.
