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.
