Speed Analog 2-Wire - Baldor VS1GV21-1B Installation & Operating Manual

5.5.8 3 Speed Analog 2-Wire

Provides 2-wire input control and allows selection of 3 Preset Speeds. The values of the Preset Speeds are set in the Level
1 Preset Speeds block, Preset Speed 1, Preset Speed 2 and Preset Speed 3. The opto inputs can be switches as shown in
Figure 5-12 or logic signals from another device.

See recommended tightening torques in Table A-2.
*Note: Remove factory jumper from J2-8 and J3-24 before connecting switch at J2-8.
J2-8 CLOSED allows normal control operation.
OPEN disables the control and the motor coasts to a stop.
J2-9 CLOSED operates the motor in the Forward direction (with J2-10 open).
OPEN motor decels to stop.
J2-10 CLOSED operates the motor in the Reverse direction (with J2-9 open).
OPEN motor decels to stop.
Note: Closing both J2-9 and J2-10 at the same time will reset a fault.
J2-11 CLOSED selects Analog Input 1.
OPEN selects Level 1 Input block, Command Source parameter.
Note: If Command Source (Level 1 Input block) is set to Analog Input 1, then Analog Input 1 is always selected
regardless of this switch position.
J2-12 CLOSED selects STOP/START and Reset Commands from the terminal strip.
OPEN selects STOP/START and Reset Commands from the keypad.
J2-13 CLOSED selects Level 1 Input block, Command Source parameter.
OPEN selects speed commanded from Keypad.
Note: When changing from Terminal Strip to Keypad (J2-12 or J2-13) the motor speed and direction will remain
the same after the change.
J2-14 Selects Preset Speeds as defined in the Speed Select Table (Table 5-8).
J2-15 Selects Preset Speeds as defined in the Speed Select Table (Table 5-8).
J2-16 Optional External Trip input (not required). If used, you must set Level 2 Drive Protect block, External Trip to "ON".
CLOSED allows normal operation.
OPEN causes an External Trip to be received by the control (when programmed to "ON").

Note: When command source is a unipolar signal (0-10V, 0-5V, 4-20mA, etc.) and forward run or reverse run is closed,
motion will occur (unless both forward run and reverse run are closed at the same time).
