Chapter 12 Description of Parameter Settings
ME300
When Pr.00-17 = 5, 6, or 7 kHz, the maximum setting for Pr.00-34 is 4.0 kHz (± 2 kHz). The
carrier frequency fluctuation range is according to the diagram below.
Auxiliary Frequency Source
Default: 0
Settings 0: Master and auxiliary frequency function disabled
1: Digital keypad
2: Communication RS-485 input
3: Analog input
4: External UP / DOWN key input
(multi-function input terminals)
7: Digital keypad potentiometer knob
Master and auxiliary frequency command selection
Default: 0
Settings 0: Master + auxiliary frequency
1: Master - auxiliary frequency
2: Auxiliary - master frequency
Master and auxiliary frequency command sets the master frequency source according to Pr.00-
20, and sets the auxiliary frequency source according to Pr.00-35. Addition and subtraction mode
of auxiliary / master frequency is set according to Pr.00-36.
When Pr.00-36 = 0, 1, 2, acceleration and deceleration by the system (includes S-curve) after
adding or subtracting the auxiliary / master frequency, can then be output as a control command.
If the value received is negative after adding or subtracting the auxiliary / master frequency, then
Pr.03-10 determines whether to change the running direction.
If you set the master frequency source (Pr.00-20 = 0) or the auxiliary frequency source (Pr.00-35
= 1) using the keypad, then the F page of the keypad displays the setting frequency that you can
use to set the master frequency or the auxiliary frequency. If the master frequency source or the
auxiliary frequency source is NOT set by keypad (Pr.00-20 ≠ 0 and Pr.00-35 ≠ 1), the F page of
the keypad displays the value after adding or subtracting the auxiliary / master frequency.
When setting the master frequency source and auxiliary frequency source, Pr.00-35 cannot be
set to the same value as Pr.00-20 or Pr.00-30.
Display Filter Time (Current)
Default: 0.100
Settings 0.001–65.535 sec.
Minimizes the current fluctuation displayed by digital keypad.
