5.7 H: Terminal Functions
Using Gain and Bias to Adjust Output Signal Level
The output signal is adjustable while the drive is stopped.
Terminal FM
1. View the value set to H4-02 (Terminal FM Monitor Gain) on the digital operator. A voltage equal to 100% of the
parameter being set in H4-01 will be output from terminal FM.
2. Adjust H4-02 viewing the monitor connected to the terminal FM.
3. View the value set to H4-03 on the digital operator, terminal FM will output a voltage equal to 0% o f the parameter
being set in H4-01.
4. Adjust H4-03 viewing the output signal on the terminal FM.
Terminal AM
1. View the value set to H4-05 (Terminal AM Monitor Gain) on the digital operator. A voltage equal to 100% o f the
parameter being set in H4-04 will be output from terminal AM.
2. Adjust H4-05 viewing the monitor connected to the terminal AM.
3. View the value set to H4-06 on the digital operator, terminal AM will output a voltage equal to 0% o f the parameter
being set in H4-04.
4. Adjust H4-06 viewing the output signal on the terminal AM.
Example 1: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.
Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.
H4-07, 08 = 0
H4-07, 08 = 1
