Control Voltage (+24 V, 0 V)
The control voltage is supplied by an external 24-V power supply unit.
Note:
•
Technical data: see page 7-9
•
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.
•
If a power supply unit is used with a DC bus dynamic
braking function, an interruption to the control voltage supply
causes braking to the axes through the DC bus dynamic
braking.
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 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.
The external 24-V power supply unit is connected to the supply unit by
cables with a cross section of 1.5 mm
2
at least. The cables must not be to
long in order to keep the claimed tolerance (
±
5%) of the control voltage.
The control voltage supply is connected by contact rails and screws (M6)
to the front of the drive controller (cross section of a contact rail:
4 x 12 mm). There are various lengths of contact rail depending on the
width of the drive controllers.
