Pr.13 Starting frequency
Set the frequency where the motor starts running.
Set the deadband in the low-speed range to eliminate noise and
offset deviation when setting a frequency with analog input.

Pr.14 Load pattern selection
You can select the optimum output characteristic (V/F characteristic)
for the application and load characteristics.
Enabled only under V/F control.
For constant-torque load (setting "0")
Pr. 14 = 0
At or less than the base

frequency voltage, the output
voltage varies linearly with the

load whose load torque is
constant if the speed varies, e.g.
conveyor, cart or roll drive.
frequency voltage, the output
voltage varies with the output
frequency in a square curve.
load whose load torque varies in
proportion to the square of the
speed, e.g. fan or pump.

Jog operation
Pr.15 Jog frequency
You can set the frequency and acceleration/decelertion time for
jog operation. Jog operation can be performed from either the
outside or PU.
Can be used for conveyor positioning, test operation, etc.

Pr.17 MRS input selection
The inverter output can be shut off by the MRS signal. The logic of
the MRS signal can also be selected.
When
Pr. 17
is set to "4", the MRS signal from external terminal
(output stop) can be changed to the normally closed (NC contact)
input, and the MRS signal from communication can be changed to
the normally open (NO contact) input.
