Pulse Follower; Plc; Digital Outputs - Baldor VS1GV21-1B Installation & Operating Manual

5.5.16 Pulse Follower

Provides electronic gearing of two or more controls from an upstream pulse reference. This mode requires expansion board
EXBHH007 and its operation is described in MN755.

5.5.17 PLC

Provides control from a PLC device (Programmable Logic Control) as described in Chapter 10 of this manual. Preset speeds
are set in software. The opto inputs can be switches as shown in Figure 5-20 or logic signals from another device.

5.6 Digital Outputs

Digital Outputs 1 and 2 are opto-isolated. Internal supply or a customer provided external power source may be used as
shown in Figure 5-21. The maximum voltage from Digital Output to common when active is 1.0 VDC.
If the Digital Outputs are used to directly drive a relay, a flyback diode rated at 1A, 100V (IN4002 or equivalent) minimum
should be connected across the relay coil. See Figure 5-21. Each opto output is programmed in the Output programming
block.
