Minimum frequency and maximum frequency
Limiting the speed setpoint
The speed setpoint is limited by both the minimum and maximum frequency.
Minimum frequency
When the motor is switched on, it accelerates to the minimum frequency regardless of the
frequency setpoint. The set parameter value applies to both directions of rotation. In addition
to its limiting role, the minimum frequency can be used as a reference value for various
monitoring functions (e.g. if a motor holding brake is engaged when the minimum frequency
is reached).
Maximum frequency
The frequency setpoint is limited to the maximum frequency in both directions of rotation. A
message is output if the maximum frequency is exceeded.
The maximum frequency also acts as an important reference value for various inverter
functions (e.g. the ramp-function generator).
