Motor cable
The motor cable may have a total
length of
25 m
if it is a standard cable type (take EMC into
consideration). If a shielded motor cable is used or if the cable is laid in a well-grounded metal duct,
the total length should not exceed
5 m
(cable shield connected to PE bilaterally).

NOTICE
Output switching
Switching a motor cable under load causes an impermissibly high load on the device. Components in
the power section may be damaged and destroyed either immediately or in the long term.
• Only switch the motor cable when the variable frequency drive no longer outputs power. I.e. the
device must be in the "ready to switch on" or "switch-on block" state.

Information
Synchronous motors or multiple-motor operation
If synchronous machines or several motors are connected in parallel to a device, the variable
frequency drive must be switched over to linear voltage/frequency characteristic curves,
(
P211 = 0 and P212 = 0).
For multiple-motor operation the total motor cable length is the sum of the individual motor cable
lengths.

2.4.2.3
Braking resistor (+B, -B)
– (from size
1
)
The +B/-B terminals are used to connect a suitable braking resistor. Select the shortest possible,
shielded link for the connection.

CAUTION
Hot surfaces
The braking resistor and all other metal components can heat up to temperatures above 70°C.
• Risk of injury due to local burns on contact.
• Heat damage to adjacent objects
Allow sufficient cooling time before starting work on the product. Check the surface temperatures with
suitable measuring equipment. Maintain an adequate distance to adjacent components.
