Description of Terminals

TB1-1 & 2 (AC INPUT)

These terminals are used for the A.C. line input. The AM-1000 accepts 115VAC. The

circuit should be able to provide a minimum of 20A.

TB1-3 & 4 (CLOSE TO ENABLE)

Closing a set of contacts across these terminals will place the drive in the RUN mode.

The motor will accelerate up to a speed determined by the signal level on terminal 10.

The drive will coast to a stop when the contacts are opened.

TB1-5 & 6 (CLOSE TO JOG)

Closing a set of contacts across these terminals places the drive in the JOG mode. The

motor will accelerate up to a speed set by the JOG potentiometer (P3).

TB1-7 & 8 (ARMATURE)

Motor lead A1 connects to terminal 7 and motor lead A2 connects to terminal 8. The

armature leads should be switched if reverse rotation is desired.

TB1-9, 10, & 11 (SPEED REFERENCE)

Typically, an external sensor is used to provide the drive with a speed reference.

Terminal 9 provides a +15VDC signal to power the sensor. The sensor provides either a

0-10mA or 0-10V signal that connects to terminal 10. Refer to switch S1. Terminal 11 is

circuit common (0V).

CN1/CN2 (MOTOR HP SELECTION)

If a 1/2HP motor is used, connect a jumper from terminal CN1 to CN2. Leave

disconnected for 1/4HP motors.

Description of Features & Adjustments

P1 MAX SPEED

This potentiometer sets the maximum motor speed when the Terminal 10 speed

reference is at maximum. Clockwise rotation increases speed.

P2 MIN SPEED

This potentiometer sets the minimum motor speed when the Terminal 10 speed

reference is at minimum. Clockwise rotation increases the output speed.

P3 JOG SPEED

This potentiometer sets the motor speed when the drive is in the JOG mode (via

terminals 5 & 6). Clockwise rotation increases the output speed.

P4 CURRENT LIMIT

This potentiometer sets the maximum motor armature current limit. Full clockwise

rotation sets a maximum current level of 3.75A when a 1/4HP motor is selected or 7.5A

when a 1/2HP motor is selected. Full counter-clockwise rotation sets current limit at 0A.

Clockwise rotation increases the maximum current limit level.

S1 SENSOR TYPE

This switch allows for either a 0-10mA or a 0-10V sensor to be used. Place S1 in the 'I'

position for current or the 'V' position for voltage.
