n F3-03: Digital Input Option DI-A3 Data Length Selection
Determines the number of bits for the option card input that sets the frequency reference.
Setting 0: 8 bit
Setting 1: 12 bit
Setting 2: 16 bit
u F4: Analog Monitor Card Settings
These parameters set up the drive for operation with the analog output option card AO-A3. This section describes
parameters that govern operation with an analog output option card. Refer to the instruction manual packaged with the
option card for specific details on installation, wiring, input signal level selection, and parameter setup.
n
F4-01, F4-03: Terminal V1, V2 Monitor Selection
Selects the data to output from analog terminal V1. Enter the final three digits of U- to determine which monitor
data is output from the option card. Some monitors are only available in certain control modes.
n
F4-02, F4-04, F4-05, F4-06: Terminal V1, V2 Monitor Gain and Bias
Parameters F4-02 and F4-04 determine the gain, while parameters F4-05 and F4-06 set the bias. These parameters are set
as a percentage of the output signal from V1 and V2 where 100% equals 10 V output. The terminal output voltage is
limited to 10 V.
Using Gain and Bias to Adjust Output Signal Level
It is possible to calibrate the meter when the drive is stopped. Follow the procedure below.
Terminal V1
1.
Use the digital operator to display the monitor gain for terminal V1 (F4-02). Make sure that the voltage output is
100% of the monitor level selection for terminal V1 (F4-01).
2. Adjust the setting to parameter F4-02 accordingly while watching the read out of the meter connected to terminal
V1.
3. Use the digital operator to display the monitor bias for terminal V1 (F4-05). Make sure that the voltage output is
0% of the monitor level selection for terminal V1 (F4-01).
4. Adjust the setting to parameter F4-05 accordingly while watching the read out of the meter connected to terminal
V1.
Terminal V2
1.
Use the digital operator to display the monitor gain for terminal V2 (F4-04). Make sure that the voltage output is
100% of the monitor level selection for terminal V2 (F4-03).
2. Adjust the setting to parameter F4-04 accordingly while watching the read out of the meter connected to terminal
V2.
3. Use the digital operator to display the monitor bias for terminal V2 (F4-06). Make sure that the voltage output is
0% of the monitor level selection for terminal V2 (F4-03).
4. Adjust the setting to parameter F4-06 accordingly while watching the read out of the meter connected to terminal
V2.
