Code Modbus ID Parameter Application RO/RW
P2.4.10 133 AI1 Joystick Offset 3 RW
This parameter defines the mid point of the analog joystick control. By moving the offset in a positive
or negative direction will cause the min frequency crossing point to be move between +/-50% of the
analog input scale.
P2.5.1 223 AI2 Mode 1,2,3 RW
Defines the analog input 2 source mode for current or voltage, also need to set DIP switches on control
board SW2 and 3.
0 = 0-20mA - current loop with an external supply the ground jumper is not required.
1 = 0-10V - If using the 10V supply on Terminal 1 of the drive, it will require a ground jumper from
Terminal 6 to the AI- input terminal 3.
2 = -10V to +10Vdc - Voltage loop with a +10 and a -10 volt differential supply.
