Activate the digital input set as DCB (
C160
) to send a DC Braking command. DC Braking duration is determined by the
following formula:
t* =
C217
* ( n
OUT
/
C219
) with n
OUT
/
C219
equal to max. 10.
Possible cases:
a)
t1 > t*
time
t1
for braking command is longer than t*.
To restart the motor following the preset acceleration ramp when DC Braking is over, just disable the DCB command
and disable and enable again the
START
command (see figure below).
