Baldor VS1MD = Preset Speed Input Bit, = Preset Speed Ramp Bit 10 = Preset Speed Ramp Bit

0 = Forward Run (FX) Command: Select to define a digital input as a forward run command in 2-wire or 3-wire control. For both 2-wire and

3-wire control, P38 – Drive Mode should be set to a 1 for normal operation. For 3-wire control an additional terminal must be defined as 17 = 3-wire operation.

1 = Reverse Run (RX) Command: Select to define a digital input as a reverse run command in 2-wire or 3-wire control. For both 2-wire and

3-wire control, P38 – Drive Mode should be set to a 1 for normal operation. For 3-wire control an additional terminal must be defined as 17 = 3-wire operation.

2 = Emergency Stop (BX) Trip: Defines a digital input as a stop command. Drive will stop according to P39 = Stop mode select (ramp deceleration, dc brake or coast to rest).

3 = Fault Reset (RST): When input is present, clears an active fault and resets the drive.

4 = Jog: When input is present, the drive ramps to the value set in Jog Frequency (F20). Jog operation overrides all other operations except Dwell operation. Therefore, if Jog frequency command is entered in the middle of Preset Speed, Up-Down or 2-wire control; operation is executed at jog frequency. A valid start command is required separate from the dedicated jog input. The jog function is only available for 2-wire control.

7 = Preset Speed Input – Bit 3:

Used to select Preset Speed 1 ~ 7 combinations, see preset speed frequencies P43~P45 and t10~t13.

8 = Preset Speed Ramp – Bit 1

9 = Preset Speed Ramp – Bit 2

10 = Preset Speed Ramp – Bit 3:

Used to define accel/decel ramp combinations for preset speeds, see (t14~t27).
