n case there is no fault signal from the internal power
section watchdogs, the signal contact BTB (drive ready)
is closed.
The contact signals to the PLC or CNC that the motor
controller is ready for operation.
The outputs have regenerating fuses.
If the tacho is not connected or broken, the voltage across the signal output
X1:28a (X2:19) is 0V.
Polarity or voltage faults cannot be detected.
The tacho fault is signalled by means of the LED 19-B.
Note:
Tachos with either a high voltage or a high inductance may cause the tacho
watchdog to malfunction. In order to overcome this problem insert a capaci-
tance of 0.1

/400V at the tacho ter and -.
In case of overload or blocked drive the signal output X1:30a (X2:18) switches
from +15V to 0V after approx. 2s.
The overload is signalled by means of the LED 19-C.
In case of a temperature increase to 90°C, the device is internally de-activated
and the fault ‘LED’ is signalled.
The BTB contact is opened. LED 19H extinguishes.
The signal output X1:16a (X2:25) switches from 0V to +15V if the speed is inferior
to 1%.
The stationary condition is signalled by means of the LED 19-D.
