10 5114 12V−electronic supply
error < 5 msec þ − − − l Error may occur as a result of a defective
angle encoder / SINCOS encoder, a
wiring error of X2 or a supply voltage
drop
l Voltage supply
l Electronics error in 931E/K, cannot be removed by
the user. Send servo positioning controller to your
Lenze representative.
11 5112 24V−electronic supply
error < 5 msec þ − − − l 24 V logic supply too high or too low
l Load capacity of 24 V logic supply is too
low, e.g. when activating the holding
brake
l Holding brake or X3 wiring error, or
overload of the brake output due to an
excessive current consumption of the
brake.
l Electronics error in 931E/K, cannot be removed by
the user. Send servo positioning controller to your
Lenze representative.

overcurrent < 10 μs þ − − − l Defective motor, e.g. winding overloaded
or charred, short circuit between
winding and housing
l Cable short circuit between two phases
or phase and shield
l Insulation of motor phase connections
l 931E/K fault (power stage defective or
insulation error − insulating foil)
15 3220 DC bus undervoltage < 1 ms ю ю ю ¨ DC bus undervoltage l Check DC bus voltage, adapt undervoltage
tripping threshold, if necessary.
16 3210 DC bus overvoltage < 1 ms þ − − − DC bus overvoltage > 70 V l Check correct functioning of power supply unit
and if the supply voltage for the power stage is
within the permissible range
(19.2 V DC ... 57.6 V DC).
l Reduce slope of deceleration ramp.
l Connect an external brake resistor to X2.
l Check if the overvoltage has been caused by other
devices connected to the DC supply of the power
stage.

l Carry out a resolver position adjustment.
l Check the selected motor data.
l Optimise the controller setting.
l Adapt the traversing profile (e.g. adapt the
acceleration ramps).
l Reduce the load torque of the motor.
