The following two switching modes are only available for V90 PTI:
These two switching modes cannot be used at the same time. Once one mode is enabled,
the other one becomes disabled. The functions of auto-tuning and gain switching must be
disabled so that the function of PI/P switching can be available. When the gain switching
function is enabled, the PI/P switching function is disabled and the settings can not be
cleared.
● Gain switching
Five gain switching modes in total are available:
– Gain switching disabled
– Gain switching using digital input signal (G-CHANGE)
– Gain switching using position deviation
– Gain switching using position setpoint frequency
– Gain switching using actual speed
If you select either of the last three gain switching modes, you need to set the conditional
threshold.
