8 PARAMETER FUNCTIONS

8.3 Selection of the Speed Command
8.3.1 Selection of the analog speed command specifications
Initial value
Pr. 73 "speed command range selection" 0
You can select the specifications of the speed command input terminals, forward/reverse rotation
operation according to the input signal polarity, and the override function.
When using the terminal 2 only, set "0" or "1" ("10" or "11" for polarity reversible operation) in this
parameter. This function can be used with other speed command terminals.
(1) When terminal 2 is used for main speed, terminal 1 for auxiliary speed, and these
signals are added for use as speed command
