M : main speed frequency command[Hz or RPM] by DRV-07 setting,
G : auxiliary speed[Hz or RPM] or gain[%],
A : auxiliary speed frequency command[Hz or RPM] or gain[%]

Of the setting types, numbers higher than 4 can do (+) or (-) motions through only analog input.
BAS-03 Aux Ref Gain : adjusts the amount of the input(BAS-01 Aux Ref Src) set as auxiliary speed.
If the auxiliary speed is set as V1 or I1 and the parameter of the terminal input group(IN) No. 01 ~ 32 is the initial
value, the auxiliary speed frequency operates as follows.
IN-65~75 Px Define : If the terminal set as No. 40 dis Aux Ref among the multi-function input terminals, the auxiliary
speed command is not active but only the main speed command is effective.
Example 1) If the frequency keypad is set in main speed and V1 analog voltage is in auxiliary speed,
Conditions:
- main speed (M) setting (DRV-07): Keypad (frequency is set at 30Hz)
- maximum frequency (Max Freq) setting (DRV-20): 400Hz
- auxiliary speed (A) setting (A:BAS-01): V1
Caution
If the maximum frequency is high, there might be an error of output frequency due to analog input and
computation error.
(frequency command by DRV-07 setting method)
Main Speed M
(frequency command by BAS-01 setting)
Auxiliary Speed A
F(M,A,G)
Auxiliary speed command is OFF when the multi-function input
terminal is set as dis Aux Ref (IN65~75).
(expresses auxiliary speed[Hz] or percentage[%] according to the computation setting condition)
