5.1
Evaluation of the ready signal
The ready signal of the regenerative power unit is revoked when a thermal overload oc-
curs in MDR60A or in case of power failure. When this message is issued, you
must
perform one of the following actions:
A Disconnect the regenerative power supply unit immediately from the power supply.
B Turn off the inverters connected to the regenerative power supply unit immediately.
C Turn off the inverters connected to the regenerative power supply unit with a delay.
D Bring the drive to a controlled stop.
Points A, B and C are concerned with the thermal protection of the unit while D is prin-
cipally concerned with stopping the drives.

gram
To protect the MOVIDRIVE
®
MDR60A against thermal overload, you have to use the
ready signal to disconnect the line contactor K11 from the regenerative power supply
unit.
The following diagram shows how the ready signal (ready) from the MDR60A regener-
ative power supply unit size 2 – 4 must be connected to the "Power on" binary input of
the inverter in order to perform evaluation in accordance with responses B... D.
