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. This parameter determines
the addition and subtraction of the master and auxiliary frequency.
When Pr.00-36 = 0, 1, 2, the control command comes after adding or subtracting the master /
auxiliary frequency and the acceleration and deceleration (including S-curve).
If the value is negative after adding or subtracting the master / auxiliary frequency, 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, 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 the keypad (Pr.00-20 ≠ 0 and Pr.00-35 ≠ 1), the F page
of the keypad displays the value after adding or subtracting the master / auxiliary 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.
When using the master and auxiliary frequency function, and the value after master and auxiliary
frequency are added or subtracted is positive, the output frequency is limited by Pr.01-00
(Maximum operation frequency); if the value is negative, the output frequency is limited by Pr.08-
67 (Master and auxiliary reverse running cutoff frequency).
Without changing the wiring and light indicator, this parameter can be used to change the
rotation direction from forward to reverse or from reverse to forward.
When using this parameter with Pr.00-23 (Motor Direction Control), Pr.00-23 has priority over
Pr.00-47.
