P2.7 178 AI1 Joystick Hyst 1, 2, 3, 4 RW

This parameter defines the joystick hysteresis between 0 and 20%. When the

joystick is turned from reverse to forward, the output frequency falls linearly to the

selected minimum frequency (joystick in middle position) and stays there until the

joystick is turned toward the forward command. How much the joystick must be

turned to start the increase of the frequency toward the selected maximum

frequency is dependent on the amount of joystick hysteresis defined with this

parameter.

If the value of this parameter is 0, the frequency starts to increase linearly

immediately when the joystick is turned toward the forward command from the

middle position. When the control is changed from forward to reverse, the frequency

follows the same pattern the other way around. See Figure 41.

Figure 41. Example of Joystick Hysteresis

In this example, the value of P1.2.9 (Sleep limit) =0.

P2.8 179 AI1 Sleep Limit 1, 2, 3, 4 RW

The frequency converter keeps on output min frequency if the AI signal level falls

below the Sleep limit defined within this parameter. This will allow the output to be

shut off after the sleep delay until converter AI signal level rises again.
