Code Modbus ID Parameter Application RO/RW
P2.4.7 178 AI1 Joystick Hyst 3 RW
This parameter is used to set the analog joystick control hysteresis around the 0 speed reference. To
ignore values around the 0 speed reference, set the value greater then 0%, this will cause a +/- dead
band around the low analog reference. With an analog signal at 0+/- this value the reference will stay at
0Hz or min speed.

P2.4.8 179 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.

P2.4.9 180 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.
