Starting Frequency (Pr. 13 ) - Mitsubishi Electric FR-S520E Series Instruction Manual

2.3.8 Starting frequency (Pr. 13
The starting frequency at
which the start signal is
turned on can be set in the
range 0 to 60Hz.
Frequency which is output
by the inverter first at a start
and gives great influence to
the starting torque. About 1
to 3Hz for vertical lift
applications, or up to 5Hz to
the maximum. For other than
vertical lift applications,
factory setting of about
0.5Hz (approx. rated motor
slip) is recommended.
Parameter Name
13 Starting frequency
CAUTION
The inverter will not start if the frequency setting signal is less than the value
set in Pr. 13 "starting frequency".
For example, when 5Hz is set in Pr. 13, the motor will not start running until the
frequency setting signal reaches 5Hz.
Note that when Pr. 13 is set to any value equal to or less than Pr. 2
"minimum frequency", simply turning on the start signal will run the motor
at the preset frequency even if the command frequency is not input.
