MOTOROLA MVME857 Sequence control module

Ready-to-operate contact BTB Ready-to-operate (BTB, terminal X3/21 and 22, max. 60V/0,5A DC) is signalled via a floating relay contact. The contact it closed when the amplifier is ready for operation. The signal is not affected by the enable signal or the I²t limit. Programmable output I/0 Terminal X3/15 (I/O) can be programmed by the I/O parameter for the following output functions (see Chapter II.2.2 for a wiring example): — I2T : signals that the preset I²t threshold (high level) has been reached — BALLAST : signals that the preset ballast limit (high level) has been exceeded

Brake 

A 24V holding-brake in the motor can be operated directly from the servo amplifier. The braking function must be explicitly enabled by using the BRAKE parameter: setting WITH. The diagram below shows the timing and functional relationship between the ENABLE signal, speed setpoint, speed and braking force During the internal ENABLE delay time of 50ms the speed setpoint of the servo amplifier is run down to 0V along a 10ms ramp. The rise and fall times of the holding brake which is built into the motor are different for the individual motor versions of the 6SM series of motors (see the manual for 6SM motors).
