Spindle
acceleration
The MANUALplus 620 permits you to define adapted acceleration values for
the speed-controlled spindle with M3/M4/M5 and for the position-controlled
spindle with M19.
In MP_maxAccSpeedCtrl and MP_maxDecSpeedCtrl you define the
acceleration and braking ramp values for the spindle in speed control (M3/M4/
M5). If the two optional parameters are not part of the configuration, the value
from MP_maxAcceleration is effective.
The additional parameters MP_limitSpeedAcc, MP_limitSpeedDec,
MP_limitAccSpeedCtrl and MP_limitDecSpeedCtrl were introduced to be
able to adapt the acceleration behavior of large, speed-controlled main
spindles better to the actual situation.

Description
MP_maxAccSpeedCtrl: M3/M4/M5 Acceleration for the spindle with shaft speed control. Also
effective for the braking ramp if MP_maxDecSpeedCtrl
is not defined.
MP_maxDecSpeedCtrl M3/M4/M5 Braking ramp for the spindle with shaft speed control
MP_maxAcceleration M19 Acceleration of spindle in position control. Also effective
for the spindle in the speed control loop if
MP_maxAccSpeedCtrl and/or MP_maxDecSpeedCtrl
are not defined.
MP_limitSpeedAcc M3/M4/M5 Limit speed for reduction of the acceleration
MP_limitSpeedDec M3/M4/M5 Limit speed for reduction of the braking deceleration
MP_limitAccSpeedCtrl M3/M4/M5 Absolute acceleration. Effective above
MP_limitSpeedAcc
MP_limitDecSpeedCtrl M3/M4/M5 Absolute deceleration during braking. Effective above
MP_limitSpeedDec.
