Adjusting the braking time
No adjustments are required, since the braking current is automatically switched off approx. 1.5s
after a motor standstill has been detected.
If no standstill is detected during the max. braking time (10s in the case of standard devices), the
braking current is switched off when this time is over. This case is indicated by the LED „ready“,
„(V9)“ (flashing 1x).
Adjusting the standstill threshold
In most applications, the factory-setting (40%) produces good results.
If the braking current is switched off before the motor has come to a rest, or if the braking current
is not switched off approx. 1.5s after the motor has come to a rest, it is possible to make an
adjustment with this potentiometer. Turn to the left --> Detection becomes more sensitive (Brake
current may switch off too soon). Turn to the right --> Detection becomes less sensitive (Braking
current may not switch off when the motor is stopped. The optimum setting has to be found by
carrying out several braking operations. The potentiometer should be changed only in little steps
(10%). For a more detailed functional description please refer to page 9.
Warning:
If the 6T3-terminal is not connected, the motor has to be supplied with
current for a period of at least 1.5s prior to the standstill. During this period of
1.5s no motor standstill is detected. The braking current then flows until the
maximum braking time has elapsed. If this is the case, the braking current
has to be adjusted to a slightly lower value.
