Operating instructions
6-52 Mounting and Installation Rexroth IndraDrive
DOK-INDRV*-FU*********-IB01-EN-P
X13, Control Voltage (+24 V, 0 V)
The external 24V supply is applied via connection X13 for
• the power section of the drive controller
• brake control via X6 and
• the control section of the drive controller
With regard to control voltage supply, the HCS02.1 drive controllers are
available in two different designs.
• Standard design HCS02.1E-W****-***N:
The control voltage is supplied by an external 24V power supply unit.
• Optional design HCS02.1E-W****-***V:
The control voltage is supplied by an integrated 24V power supply unit.
A power supply unit that makes available the control voltage supply for the
power section and the control section from the DC bus is integrated in the
drive controller.
Note: • Falling short of the permissible control voltage leads to a
corresponding error message (=> refer also to firmware
function description).
• Interruption to the control voltage when the motor is
running leads to torque-free (brakeless) runout in the motor.
Note on design -***V:
• The brake supply has to be realized via an external power supply unit.
• Applying the external supply voltage for the purpose of buffering at no-
power operation is allowed.
• Load at the terminal X13 is not allowed.
DANGER
Dangerous movement caused by brakeless
motor coasting to stop in the event of an
interruption to the control voltage supply!
Do not stay within the motional range of the
machine. Possible measures to prevent personnel
from accidentally accessing the machine:
– protective fencing
– protective grid
– protective cover
– light barrier.
Fencing and covers must be adequately secured
against the maximum possible force of movement.
