MSC-3 Start Up
C03 RAMP
The MSC-3 has a programmable Ramp with adjustable acceleration, deceleration and S-curve rates.
Individual parameters are provided for the linear and curved portions of the ramp. These parameters are
found within the C03 Ramp menu.
C030 ACCEL TIME
C030 ACCEL TIME
10.0 sec
Range: 0.5…600.0 seconds
• Press

to edit the value.
• Press ▲ / ▼ to make changes to the value.
• Press

to accept the new value OR
• Press ESC to abandon the value change.
The C030 ACCEL TIME is the time taken for the motor to go from zero speed up to motor rated speed
(assuming minimum C032 S TIME ). An MSC-3 with B03 MOTOR Hz set to 50 Hz and
C030 ACCEL TIME set to 10.0 seconds will take 10 seconds to go from 0 Hz to 50 Hz.
C031 DECEL TIME
C031 DECEL TIME
10.0 sec
Range: 0.5…600.0 seconds
• Press  to edit the value.
• Press

▼
to make changes to the value.
• Press  to accept the new value OR
• Press
ESC
to abandon the value change.
The
C031 DECEL TIME
is the time taken for the motor to go from motor rated speed down to zero
speed (assuming minimum
C032 S TIME
). An MSC-3 with
B03 MOTOR Hz
set to 50 Hz and
C031 DECEL TIME set to 10.0 seconds will take 10 seconds to go from 50 Hz to 0 Hz.
C032 S TIME
C032 S TIME
0.01 sec
Range: 0.01…40.00 seconds
• Press

to edit the value.
• Press ▲ / ▼ to make changes to the value.
• Press

to accept the new value OR
• Press ESC to abandon the value change.
The C032 S TIME is the time taken for the motor to reach the limit of acceleration (as set by the rated
speed and the C030 ACCEL TIME or C031 DECEL TIME ). Using the C032 S TIME ensures smooth
speed increases and decreases. A long C032 S TIME interval will yield a smoother speed transition,
however the C032 S TIME will extend the overall ramping time. The ramp time is approximately equal to
the
C032 S TIME
plus
C030 ACCEL TIME
or
C031 DECEL TIME
.
