Operating characteristics
The regenerative power supply unit permits safe operating characteristics at an over-
load capacity of I
N
= 150 % for at least 60 s when maintaining the power supply system
prerequisites.
7.1.1
Inhibit inverter of regenerative power supply unit
To keep the power supply disturbances to a minimum, you can inhibit the inverter of the
regenerative power supply unit using a DC 24 V signal at terminal X3:3 (inhibit). For the
MOVIDRIVE
®
MDR60A0150/0370/0750 regenerative power supply unit (size 2 – 4), the
minimum inhibit time is 1.5 s. If the DC 24 V signal is active for < 1.5 s, the regenerative
power supply unit remains inhibited for 1.5 s. Then, once the inhibit signal is removed,
the regenerative power supply is immediately enabled.
MOVIDRIVE
®
MDR60A0150/0370/0750 (size 2 – 4) displays the "Ready" even when in-
hibited. Take this fact into account in your system's sequence control.
