Note:
The default value for the parameter
State transition 5 392 is operation
mode "2 – Ramp". For confi
urations with torque control, the defaul
value is operation mode "0 - Coast to stop". In a switch-over of the
configuration, the setting value for
State transition 5 392 is also altered if
necessary.
If transition 5 has been triggered with
State transition 5 392 = "1 - DC brake“, a new
control word is only accepted after the completion of the transition process. The
change of state from "Operation enabled“ to "Ready“ is done after the expiry of the
time
Braking time 632 parameterized for the DC brake.
If the parameter
State transition 5 392 = "2 - Ramp“ has been set, the control word
can be set back to 0x0F durin
g the stoppage of the drive. In this way, the drive runs
back up to its set reference value and remains in the state "Operation enabled“.
The change of state from "Operation enabled“ to "Ready“ is done after the set switch-
off threshold has been reached and expiry of the set holdin
time (equivalent to the
behavior in a quick stop). In this, the parameters
Switch-off threshold
637 (percent of
fmax) and
Holding time 638 (holding time after switch-off threshold reached) are
relevant.
