Parameter Description
4-18 Current Limit
Range: Function:
Size [ 1.0 - Enter the current limit for motor and
related 1000.0 %] generator operation. To protect the
*
motor from reaching the stalling torque,
the default setting is 1.1 x the rated
motor torque (calculated value). If a
setting in 1-00 Configuration Mode to 1-26
Motor Cont. Rated Torque is changed,
4-18 Current Limit is not automatically
reset to the default setting.
4-19 Max Output Frequency
Range: Function:
Size [ 1 - Enter the maximum output frequency
related 1000.0 Hz] value. 4-19 Max Output Frequency
*
specifies the absolute limit on the
adjustable frequency drive output
frequency for improved safety in
applications where accidental
overspeeding must be avoided. This
absolute limit applies to all configu-
rations and is independent of the setting
in 1-00 Configuration Mode. This
parameter cannot be adjusted while the
motor is running.
NOTICE!
When 1-10 Motor Construction is set to [1] PM, non-salient
SPM, the maximum value is limited to 300 Hz
3.6.3 4-5* Adj. Warnings
Define adjustable warning limits for current, speed,
reference and feedback.
NOTICE!
Not visible in display, only in MCT 10 Set-up Software.
Warnings are shown on display, programmed output or
serial bus.
