Block monitoring This monitoring function checks the motor speed and the motor current.

If both of the following conditions are met for the period „block monitoring time“, then the
error/the warning „drive blocked“ is signaled to the controller and an immediate pulse in-
hibit takes place.
m Motor speed = 0
m The motor current output from the device is the same as the set motor limit current (cur-
rent limit).
Signal bus All power units at the axis devices are connected with a „signal bus“. Each user can re-
quest for and set the bus signals including the supply unit.
Signal bus - supply ready-for-use
Indicates, when the supply unit is in the status „ready-for-use“. This signal is generated
after the recognition and identification of the power supply. At a power rectifier „ready-for-
use“ is active after about 4 s after switching on the 24 V-supply voltage.
At power supply errors and power supply failure the ready-for-use signal is reset. The
axes must react upon this and must change into the error state.
Signal bus - ballast resistor on
The DC-link voltage is monitored independently by each axis. The mode parameter
(140.1) bit 0 sets, if the signal for the control of the ballast resistor shall be activated at
this warning. If the voltage of the ballast resistor drops below the ballast resistor threshold
(P130.29 protected) - 20 V (hysteresis) the axis resets the signal at the bus and deletes
the warning.
The ballast resistor threshold is calculated from max. U
