3: Auxiliary frequency reference.
• When F19.00 = 4 (auxiliary frequency reference is set by AI analogue), the auxiliary frequency
will be set by the input voltage value corresponding to the analogue source which selects this
function.
4: Process PID reference.
• When F04.01 = 1 (process PID reference is set by AI analogue), the process PID reference will
be set by the input voltage value corresponding to the analogue source which selects this
function.
5: Process PID feedback.
• When F04.02 = 0 (AI analogue inputs process PID feedback), the process PID feedback will be
set by the input voltage value corresponding to the analogue source which selects this function.
6: Process PID regulating upper limit.
• When F04.11 = 1 (upper limit value of the PID regulator is set by AI analogue), the process PID
regulating upper limit will be set by the input voltage value corresponding to the analogue
source which selects this function.
7: Process PID regulating lower limit.
• When F04.12 = 1 (lower limit value of the PID regulator is set by AI analogue), the process PID
regulating lower limit will be set by the input voltage value corresponding to the analogue
source which selects this function.
Analogue input AI4 function selection
8: Motor overheating signal input.
• Connect electronic thermistor embedded
motor stator coils to the inverter’s
analogue input, as the right figure.
• Refer to parameters F20.06 and F20.07
about the thermistor.
• Refer to parameters F16.00－F16.03
about the range of 1－7.
Note: Only when using HD30-EIO will F16.03
and F16.04 (analogue inputs AI3 and AI4) be
enabled.
