8.4.2.7 Actual value monitoring
If an actual value monitoring time > 0 s is selected in C02593/1
, the actual speed time
monitoring is active.
The monitoring time starts when the speed setpoint has reached the lower switching
threshold and the actual speed is still above this threshold. (see illustration [8-11]
in
chapter "Process when brake is closed
".)
If the actual speed is still above the threshold when the monitoring time has expired,
the brake will be automatically applied in the automatic brake control mode (mode 12).
n Motor magnetising time
CINH = controller inhibit
When an asynchronous motor is used,
first the magnetic field required for the
holding torque is created (which is
already available when a synchronous
motor is used) after the controller
inhibit is deactivated.
The motor is internally magnetised
through internal feedforward control
of the lower speed threshold. The
release time set in C02589/2
is
considered here.
Note!
In the Lenze setting, the actual speed time monitoring is deactivated
(C02593/1
= "0 s"), i.e. the brake will only be applied when the actual speed has
reached the lower switching threshold.
