For the braking currents applicable to the respective braking times please refer to the table under
point 7. By using an integrated monitoring function, the device protects itself against overloading
caused by a too high braking frequency. For commissioning or setting-up purposes, 5 braking
operations in direct succession are allowed. If exceeding of the permissible maximum braking
frequency is detected, the motor will be interlocked against switch-on (In the case of the special
version SO1, overloading is only indicated. The motor is not interlocked against switch-on). This
interlock can be reset only by switching off the operating voltage.
Faults occuring during braking are indicated via a flashing mode.
If the motor is to be restarted during a braking operation, it is first of all necessary to stop the
braking operation. For this, the contact X3-X4 is to be opened for the least 150ms. When the
contact X3-X4 is reclosed, the motor can be restarted after 1200ms.
Note: If the braking time at rated device current is too short, due to the fact that the
centrifugal masses to be slowed down are too large, a device featuring a
higher rated current has to be used.
