Note
Positions of the threshold switches
The threshold switches for the braking modules are positioned on the panel as follows:
• Braking modules for frame sizes FX, FB, GX, and GB: Position "1" is up; position "2" is
down
• Braking modules for frame sizes HX and JX: Position "1" is at the back; position "2" is at
the front
Note
"Overvoltage" fault
Even when the response threshold is set to the low value, the DC link voltage can still reach
the maximum voltage value (hardware shutdown threshold), thus triggering the
"Overvoltage" fault. This can occur, for example, in cases where there is too much
regenerative energy for the available braking power.
To prevent the DC link voltage from exceeding the threshold, the Vdc-max controller must be
enabled (p1240) and the device supply voltage set accordingly (p0210).
