6. Repeat step 11.1 using different positive or negative values for the
D/A Level. Verify the meter reads the values you enter.
Testing Analog Output 2
1. Disable the drive, by opening the connections between the
ENABLE input and the + 24 VDC.
2. Disconnect the connections to J1-31.
3. Select O u tput Diagnostics icon from the Drive Window.
4. From the Output Diagnostics window select Analog Output 2 .
5. Enter 1000 in the D/A level box.
6. Connect a DC voltmeter across analog test points A2 and COM.
The meter should read approximately 1 VDC.
7. Repeat step 11.1 using different positive or negative values for the
D/A Level. Verify the meter reads the values you enter.
If either output is defective, return the unit for repair.
Testing Positive and Negative Current Limits
The following tests verify the functionality of the analog +I LIMIT
and -I LIMIT inputs.
The tests require:
●
a PC running ULTRA Master, and
●
a 10 kOhm potentiometer.
Testing Positive Current Limit
1. Verify the accuracy of the potentiometer with an ohmmeter before
installing.
2. Disable the drive by opening the connections between the
ENABLE input and +24VDC.
3. Disconnect the connections to J1-27 and J1-28.
4. Connect the 10K potentiometer between J1-27 and J1-28.
Refer to “J1 – Controller” on page 6-1 for a diagram showing the
location of the pins and Figure 6.44 on page 6-45 for an intercon-
nect diagram.
5. Choose the Drive S ignals command icon from ULTRA Master.
6. Choose S et Up , if the Drive Signals Set Up window is not already
active.
7. Choose Current - Input Limit + as the analog signal.
