Name Delivery Setting range
Vmin boost 0.0 % [0.0 ... 100.0] % Boost of the motor voltage in the range of low
speeds.
In the case of conveyor applications with an
inclined proportion, a turn−back during
start−up can be prevented.
Typical values approx. < 5%.
Imax in motor mode Device−depende
nt [0.00 ... Imax] A Maximum motor current
MSEMAxx063−42: 5.6 A
MSEMAxx080−32: 13.2 A
With a gearbox, the setting range can be
smaller.
Reduction of I
max
limits the load−dependent
starting torque.
Motor overload setting (I 2 xt) 100.00 % [0.00 ... 250.00] % Setting for operation at an ambient
temperature of up to + 40 °C optimised.
Starting value for motor
overload (I
2 xt)
50.00 % [0.00 ... 100.00] % Recommended setting for operation
according to UL: 50.00 %
Motor brake switching
threshold 100 rpm [0 ... 499.9/i] rpm Motor brake is switched if the value is
exceeded or is too low.
Higher value:
In the case of conveyor applications with an
inclined proportion, a turn−back during
start−up can be prevented.
Brake resistor R 150.0 Ohm [150.0 ... 500.0] Ohm Enter data of a connected brake resistor.
The optional internal brake resistor is set by
default.
Rated power of brake resistor 10 W [10 ... 65535] W
Thermal capacity of brake
resistor 0.6 kWs [0 ... 6553.5] kWs
Reduction of brake chopper
threshold 0 V [0 ... 150] V The threshold is reduced by the voltage value
set here.
The switching threshold is adapted to the
different mains voltage ranges.
Reduction by 20 ... 30 V can prevent
overvoltage for operation in generator mode.
Impact of oscillation damping 5.00 % [0.00 ... 250.00] % To suppress idle oscillations. Typically, the
impact has to be increased for this purpose.
Oscillation damping filter time 50 ms [2 ... 250] ms
