Setting E: Motor Temperature
In addition to motor overload fault detection oL1, it is possible to use a Positive Temperature Coefficient (PTC) thermistor
for motor insulation protection. Refer to Motor Protection Using a Positive Temperature Coefficient (PTC) Thermistor on
page 236 for a detailed explanation.
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The difference of the PID feedback
input value and the differential feedback input value builds the feedback value used to calculate the PID input. Refer to PID
Feedback Input Methods on page 161.
Setting 17: Motor Thermistor (NTC)
Used as a complement or a substitution for oL1. Refer to Motor Protection Using an NTC Thermistor Input on page 238
for details.
Setting 1F: Through Mode
An input does not affect any drive function, but the input level can still be read out by a PLC via a communication option or
MEMOBUS/Modbus communications.
Setting 25: Secondary PI Setpoint
10 V = S3-02 (maximum output frequency)
Setting 26: Secondary PI Feedback
10 V = S3-02 (maximum output frequency)

H4: Multi-Function Analog Outputs
These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive
performance.

H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection
Sets the desired drive monitor parameter Uo-oo to output as an analog value via terminal FM and AM. Refer to U: Monitor
Parameters on page 286 for a list of all monitors. The “Analog Output Level” column indicates whether a monitor can be
used for analog output.
Example: Enter “103” for U1-03.
No. Name Setting Range Default
H4-01 Multi-Function Analog Output Terminal FM Monitor Selection 000 to 999 102
H4-04 Multi-Function Analog Output Terminal AM Monitor Selection 000 to 999 103
A setting of 031 or 000 applies no drive monitor to the analog output. With either of these settings, the output level of the
terminals FM and AM can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).
n
H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
H4-05, H4-06: Multi-Function Analog Output Terminal AM Gain and Bias
Parameters H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameters H4-03 and H4-06 set the terminal FM and AM output signal level when the value of the selected monitor
is at 0%. Both are set as a percentage, where 100% equals 10 Vdc or 20 mA analog output and 0% equals 0 V or 4 mA. The
output voltage of both terminals is limited to +/-10 Vdc.
The output signal range can be selected between 0 to +10 Vdc or -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. Figure 5.63 illustrates how gain and bias settings work.
No. Name Setting Range Default
H4-02 Multi-Function Analog Output Terminal FM Gain -999.9 to 999.9% 100.0%
H4-03 Multi-Function Analog Output Terminal FM Bias -999.9 to 999.9% 0.0%
H4-05 Multi-Function Analog Output Terminal AM Gain -999.9 to 999.9% 50.0%
H4-06 Multi-Function Analog Output Terminal AM Bias -999.9 to 999.9% 0.0%
Using Gain and Bias to Adjust Output Signal Level
The output signal is adjustable while the drive is stopped.
