Minimum Motor Speed Frequency At The Motor Start Up - Mitsubishi Electric FR-E800 Instruction Manual

9.5
Minimum motor speed frequency at the motor start
up
PM PM PM
Set the frequency where the PM motor starts running.
Set the deadband in the low-speed range to eliminate noise and offset deviation when setting a frequency with analog input.

 Starting frequency setting (Pr.13)
• The frequency where the PM motor starts running can be set in the range of 0 to 60 Hz.
• When the frequency command specifies the frequency less than the one set in Pr.13 Starting frequency, the PM motor
is stopped.
When the frequency command specifies the frequency equal to the set frequency or higher, the PM motor accelerates
according to the setting of Pr.7 Acceleration time.

NOTE
• Under induction motor control (under V/F control, Advanced magnetic flux vector control, Real sensorless vector control, and
Vector control), the output starts at the frequency set in Pr.13. Under PM sensorless vector control, the output always starts
at 0.01 Hz.
• The inverter does not start if the frequency setting signal has a value lower than that of Pr.13. For example, while Pr.13 = 20
Hz, the inverter output starts when the frequency setting signal reaches 20 Hz.
CAUTION
• Note that when Pr.13 is set to a value equal to or lower than Pr.2 Minimum frequency, simply turning ON the start signal
runs the motor at the frequency set in Pr.2 even if the command frequency is not given.
