If the total of the temperature values is greater than 10 K, the harmonics
have to be reduced by means of appropriate measures.
Current Reduction in the Case of Overtemperature
The mains filters recommended by Rexroth have been dimensioned for
an ambient temperature of 45°C.
For higher temperatures reduce the mains current according to the
following formula:

15.6 Determining the Data for Selecting the 24V Supply
At HCS02 and HLB01.1C devices the external 24V supply takes place via
the connection X13, at the devices HCS03, HMS01, HMD01, HLB01.1D
and HMV01 via the connections 24V and 0V at the terminal block.
Via these connections the devices are supplied with 24V for
• the power section of the drive controller
• brake control via X6 and
• the control section of the drive controller.
The following performance data are required for selecting the control
voltage supply:
• nominal voltage of supply
• continuous current capacity of supply
• peak current capacity of supply
