Setting 30: During Torque Limit

The output closes when the motor is operating at the torque limit specified by the L7-oo parameters or an analog input. This

setting can only be used in OLV control mode.

H3-01: Terminal A1 Signal Level Selection

Selects the input signal level for analog input A1.

No. Name Setting Range Default

H3-01 Terminal A1 Signal Level Selection 0 to 3 0

Setting 0: 0 to 10 Vdc

The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and bias

settings will be read as 0%.

Setting 1: 0 to 10 Vdc Bipolar

The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the

motor will rotate in reverse.

Setting 2: 4 to 20 mA

Setting 3: 0 to 20 mA

H3-02: Terminal A1 Function Selection

Selects the input signal level for analog input A1.

No. Name Setting Range Default

H3-02 Terminal A1 Function Selection 0 to 26 0

H3-03, H3-04: Terminal A1 Gain and Bias Settings

Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (gain).

Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1 (bias).

Use both parameters to adjust the characteristics of the analog input signal to terminal A1.

No. Name Setting Range Default

H3-03 Terminal A1 Gain Setting -999.9 to 999.9% 100.0%

H3-04 Terminal A1 Bias Setting -999.9 to 999.9% 0.0%

Setting Examples

• Gain H3-03 = 200%, bias H3-04 = 0, terminal A1 as frequency reference input (H3-02 = 0):

A 10 Vdc input is equivalent to a 200% frequency reference and 5 Vdc is equivalent to a 100% frequency reference. Since

the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will be equal to E1-04

above 5 Vdc.

Figure 4.37 Frequency Reference Setting by Analog Input with Increased Gain

• Gain H3-03 = 100%, bias H3-04 = -25%, terminal A1 as frequency reference input:

An input of 0 Vdc will be equivalent to a -25% frequency reference.

When parameter H3-01 = 0, the frequency reference is 0% between 0 and 2 Vdc input.
