Information
Torque limitation during active setpoint delay
(P107 / P114)
During an active setpoint delay, the torque is limited to a maximum of 160% of the rated
torque. This prevents the occurrence of excessive currents in the inverter or breakdown of the
motor if
• For application of the brake, the brake reaction time (P107) is set too long.
• For release of the brake, the value for the absolute minimum frequency (P505) is set too
high.

P114 = 0.02...0.4 s *
P107 = 0.02...0.4 s *
P201…P208 = Motor data
P434 = 1 (ext. brake)
P505 = 2...4 Hz
for safe start-up
P112 = 401 (off)
P536 = 2.1 (off)
P537 = 150 %
P539 = 2/3 (I

monitoring)
to prevent load drops
P214 = 50...100 % (precontrol)
* Settings (P107/114) depending on
brake type and motor size. At low power
levels (< 1.5
kW) lower values apply for
higher power ratings (> 4.0
kW) are
larger values.
