Auxiliary Frequency Source
Default: 0
Settings 0: Master and auxiliary frequency function disabled
1: Inputs from digital keypad
2: Inputs from RS-485 communication
3: Inputs from analog input
4: Inputs from external UP / DOWN (multi-function input terminals)
5: Pulse inputs without direction command (refer to Pr.10-16)
6: CANopen communication card
8: Communication card

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 master frequency source (Pr.00-20 = 0) or the auxiliary frequency source (Pr.00-35 = 1)
by 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 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.
 When using the master and auxiliary frequency function, after the master and auxiliary
frequencies are added or subtracted, if the value is positive, the output frequency will be limited
by the maximum operating frequency (Pr.01-00); if the value is negative, the output frequency
will be limited by reverse running cutoff frequency (Pr.08-67) for limiting.

0: Standard
1: Exchange the rotation direction
 Without changing the wiring, this parameter can be used to change the rotation direction from
forward to reverse or from reverse to forward, and the indicator light won’t be changed.
 When using this parameter with Pr.00-23 (Control of motor direction), Pr.00-23 has priority over
Pr.00-47.
