Analog Outputs; Opto-Isolated Inputs - Baldor VS1GV21-1B Installation & Operating Manual

5.3 Analog Outputs

Two programmable analog outputs are provided on J1-6 and J1-7. These outputs are scaled and can be used to provide
status of various control conditions. The return for these outputs is J1-1 analog return. Each output function is programmed
in the Level 1 Output block, Analog Out1 Signal or Analog Out2 Signal parameter values.
Analog Output 1 can be set for voltage or current mode operation. With JP2 as shown in Figure 5-3, Voltage mode is
selected. If JP2 is connected to pins 2 and 3, current mode is selected.
The Level 1 Output Setup Parameter P1510 can be set to the full scale voltage or current range desired.

5.4 Opto-Isolated Inputs

Logic input connections are made at terminal strip J2 pins 8 to 16. J2 inputs can be wired as Active High or Active Low as
shown in Figure 5-4. Internal or external power source is selected by jumpers JP5 and JP6 shown in Figure 5-4.
Notes for Figure 5-4:
1. See operating modes defined later in this chapter for input usage.
2. Factory connection of J2-8 (Enable) is made to J3-24 for Internal, Active Low connection. For other configurations, the
wire at J3-24 must be moved to J3-23, J3-21 or J3-22 as needed.
