48 BU 0180 en-4118
For multiple motor operation the total motor cable length consists of the sum of the individual cable
lengths.
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 frequency inverter no longer pulses, i.e. the device must be in the state
"ready for switch-on" or "switch-on block".
Information
Synchronous motors or multiple motor operation
If synchronous machines or several motors are connected in parallel to a device, the frequency inverter must be
switched over to linear voltage/frequency characteristic curves,

P211 = 0 and P212 = 0.
For multiple motor operation the total motor cable length consists of the sum of the individual motor cable lengths.
2.4.2.3 Braking resistor (+B, -B) – (from size 2)
The terB/ -B are intended for the connection of a suitable braking resistor. A short screened
connection should be selected.
CAUTION
Hot surfaces
The braking resistor and all other metal components can heat up to temperatures above 70°C.
• Danger 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 or provide protection against
contact.
