Motor reference speed
In
C00011 the reference speed of the motor must be set.
Maximum current
In
C00022 the required maximum current must be set.
• To avoid that the motor starts unintentionally without adjusting the plant data, the maximum
current in the Lenze setting is set to "0 A" in C00022 .
Ultimate motor current I
ULT
C00620 serves to check the set ultimate motor current I
ULT
.
The ultimate motor current I
ULT
is a limit value to protect the motor from destruction or influence
of the rated data.
• This limit value must not be travelled cyclically in the drive process.
• The maximum current parameterisable in
C00022 should have a sufficient distance from this
limit value.
• If the instantaneous value of the motor current exceeds the limit value set in C00620 the
response set in C00619 is executed for motor protection (Lenze setting: Fault).
Maximum motor speed
Adapt the maximum motor speed in
C00596 and select the error response required when this speed
limit has been reached in C00607 .

Note!
From the perspective of the application it has to be ensured that a maximum of 100 %
of the reference speed set in C00011 is requested as speed setpoint.
When using MCS motors, please observe the following:
The controller with software version V01.xx does not support a field weakening control
for synchronous motors, so that for this version the operation of MCS motors at the
voltage limit may present an undefined behaviour.
Therefore, it should be detected whether the motor used exceeds the voltage limit
within the desired operating range up to the maximum current/reference speed. If so,
the reference speed must be reduced to a value permissible with regard to voltage.

Note!
When you select a Lenze motor from the catalogue and transfer the plant parameters of
the motor to the controller, the setting in C00620 is automatically adjusted to the
selected motor.
