AI1 Sleep Limit
3
RW
This parameter defines the sleep frequency level in the joystick control mode. The output of the drive turns
off if the joystick reference stays below the sleep limit for longer than the sleep delay time parameter
Para ID 180.

AI1 Sleep Delay
3
RW
This parameter defines the joystick sleep delay time. If the joystick reference is below the sleep limit level for
the time defined the output of the drive will shutoff and be in sleep mode. Sleep function is disabled when
this value is set to 0.

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 b/-50% of the analog
input scale.

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.
