Setting 9: Output Frequency Lower Limit Level

The user can adjust the lower limit of the output frequency using an analog input signal.

Setting B: PI Feedback

Supplies the PI feedback value. This setting requires PI operation to be enabled in b5-01.

Refer to PI Feedback Input

Methods on page 129

.

Setting C: PI Setpoint

Supplies the PI setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PI setpoint. PI

operation to be enabled in b5-01 to use this setting.

Refer to PI Setpoint Input Methods on page 128

.

Setting D: Frequency Bias

The input value of an analog input set to this function will be added to the frequency reference. This function can be used with

any frequency reference source.

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.

Setting F: Through Mode

When set to F, an input does not affect any drive function, but the input level can still be read out by a PLC via a BACnet

communication or MEMOBUS/Modbus communications.

Setting 16: Differential PI Feedback

If an analog value is set for this function, the PI controller is set for differential feedback. The difference of the PI feedback

input value and the differential feedback input value builds the feedback value used to calculate the PI input.

Refer to PI

Feedback Input Methods on page 129

.

Setting 1F: HAND Reference

Sets the frequency reference when in HAND Mode and parameter Z1-41, HAND Speed Reference Selection, is set to 1

(Analog).

Note:

Setting 1F is “HAND Reference” in bypass controller software versions VST800298 and later.

Setting 1F: Through Mode

Set this value when using the terminal in the pass-through mode.

Note:

Setting 1F is “Not Used (Through Mode)” in bypass controller software versions VST800297 and earlier.

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 194

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.

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).
