Lenze i750 - Motor Holding Brake Connection

Motor holding brake c
onnecon
The inverter is designed for 24 V brakes. A motor holding brake is connected to X106 and
supplied via X107.
DANGER!
Loss of the safe isolaon
Sa
fe isolaon of the control card from the mains potenal is deacvated when the motor and
motor holding brake are connected via a system cable AND X5 and X107 are supplied by a
common power supply unit. This also applies when using a SELV/PELV power supply unit.
Possible consequences: Electric shock in the event of a fault.
▶
Supply X107 and X5 by separate SELV/PELV power supply units if the motor and motor
holding brake are connected via a system cable.
X107 and X5 can be supplied by a common SELV/PELV power supply unit if the
mot
or and motor holding brake are connected via safely isolated installed
cables.
When the motor holding brake is open, a slight knocking sound can be noced
in the mot
or. This stems from test pulses for monitoring the motor brake
control.
