H4: Multi-Function Analog Outputs - YASKAWA U1000 Series Technical Manual

5.7 H: Terminal Functions
Setting E: Motor temperature
In addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient)
thermistor for motor insulation protection. Connect the PTC to analog input terminal A3, and set switch S4 on the
terminal board to PTC. Refer to
Motor Protection Using a Positive Temperature Coefficient (PTC) on page 260
Setting F, 1F: Through mode
When set to F or 1F, 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 10, 11, 12, 15: Forward, Reverse, Regenerative, General torque limit (OLV, CLV, AOLV/PM, CLV/PM)
These functions can be used to set a torque limit using analog inputs for different operating conditions. Refer to
Torque Limit on page 274
Setting 13: Torque Limit Using Torque Reference/Speed Limit
When using Torque Control, an analog input programmed to this function can set the torque reference (when in Torque
Control) or the torque limit (when in Speed Control). Refer to
Compensation Values on page 201
Setting 14: Torque compensation
Used to set a torque compensation value when using Torque Control. Refer to
Limit, and Torque Compensation Values on page 201
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The subtraction of the PID
feedback input value and the differential feedback input value builds the feedback value that is used to calculate the PID
input. Refer to PID Feedback Input Methods on page
Setting 30, 31, 32: DriveWorksEZ Analog Input 1, 2, 3
These settings are for functions used in DriveWorksEZ. Normally there is no need to change or apply these settings.
 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 U- to output as an analog value via terminal FM and AM.
Monitors on page 456 for a list of all monitors. The "Analog Output Level" column indicates if a monitor can be used
for analog output.
Example: Enter "103" for U1-03.
No.
H4-01
H4-04
A setting of 031 or 000 applies no drive monitor to the analog output. With this setting, terminal functions as well as FM
and AM output levels can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).
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
Parameter H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameter 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, -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. Figure 5.84 illustrates how gain and bias settings work.
