Figure 4.5-d Input Interface for Analog Single-ended Potentiometer
●
The input voltage of the analog value should not exceed the range of -10V-+10V; otherwise the driver will be
damaged.
●
The analog value has a deviation indeed, because wires and the interface circuit, etc, weaken and are interfered.
It is suggested that a cable with a shielding layer be used for connection with its both ends grounded. Parameter
PA49 can be used to set the threshold voltage (unit: rpm).
●
The analog value has a deviation indeed, so it must be adjusted. Parameter PA45 can be used to make
compensate for the deviation value.
