6-36 Electrical Data Rexroth IndraDrive C
DOK-INDRV*-HCS02.1****-PR02-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: • Technical data: see page 6-18
• 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 (see also page 6-18):
• 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.
