General Information
Damage to the supply unit!
NOTICE
At HMV01.1R supply units, there must be at least 10 ms between the request
mains OFF (signal at X32.6 / X32.7) and the disconnection of the mains volt‐
age, so that the energy flow has been interrupted when the disconnection
process starts.
You can make sure this order is observed by appropriate switch elements
(e.g. by a main switch of the control cabinet with leading auxiliary contact).
For this purpose, connect the auxiliary contact in series with mains OFF.
Do not switch on HMV supply units simultaneously!
In the switch-on sequence of the supply unit, the supplying mains
is loaded with the current I
L_trans_max_on
for the purpose of analysis.
During the unloading process, voltage overshoot can occur at the
mains components connected in the incoming circuit (e.g. mains
filters) due to inductances connected in the incoming circuit, e.g.
the leakage inductance of the mains transformer.
With 3 or more HMV supply units at the common supply mains:
Switch on supply units one after the other with a time interval of at
least 0.5 seconds so that the inrush currents are not added.
Control Circuits HMV

●
Deceleration in the case of disturbed electronic system of drive
●
Deceleration in the case of emergency stop or mains failure
●
Control by emergency stop relay with DC bus short circuit
●
Control by emergency stop relay without DC bus short circuit
●
Control by control unit
●
