Requirements on the brake cables
ƒ
Use a Lenze system cable with integrated brake cable.
–
The shielding of the brake cable must be separated.
ƒ
Length: max. 50 m
ƒ
If a separately installed brake cable is required, lay it in a shielded manner.
)
Note!
Due to the monitoring circuit of the brake connection, an additional
constant voltage drop of 1.5 V is produced. The voltage drop can be
compensated by a higher voltage at the cable entry.
The voltage required at X6/B+ and X6/B− for the Lenze system cables is
calculated as follows:
