ADJUSTM ENTS

CCW = Counter-ClockWise position

CW = ClockWise position

MAX SPD Maximum Speed

ANALOG MODE only.

Not an absolute speed limit. Calibration to reference.

At CCW, with 10VDC input, generates a VCO frequency of 1200 Hertz.

At CW, with 10VDC input, generates VCO frequency of 10 Kilohertz.


JOG SPD Jog Speed

ANALOG MODE only.

Sets speed during JOG mode.

CCW is zero Jog Speed.

CW is a jog speed of about 30% of full speed.

Direction is set by jumper (see page 34).


ACCEL Acceleration time

ANALOG MODE only.

Sets amount of time to change from zero speed to full speed.

With JP2in the R/L position, CCW is about 20 seconds.

With JP2in the DIR position, CCW is about 0.05 seconds.

With JP2in the R/L position, CW is about 0.5 seconds.

With JP2in the DIR position, CCW is about 0.05 seconds.


DECEL Acceleration time

ANALOG MODE only.

Sets amount of time to change from full speed to zero speed.

With JP2in the R/L position, CCW is about 20 seconds.

With JP2in the DIR position, CCW is about 0.05 seconds.

With JP2in the R/L position, CW is about 0.5 seconds.

With JP2in the DIR position, CCW is about 0.05 seconds.


GAIN

Gain adjust

ANALOG and DIGITAL modes.

Sets the stiffness of the motor shaft.

Zero position is where the shaft should be at any point in time.

Motor amps is proportional to offset of the shaft from the zero position.

Stiffness is motor amps per degree of shaft offset from zero position.

CCW is about 0.56% of full load current per degree of offset.

CW is about 5.6% of full load current per degree of offset.

Normal Gain setting is between CCW and 50% of rotation.


STAB

Stability adjust

ANALOG and DIGITAL modes.

Sets the stability of the motor under load.

CCW makes the drive more sluggish.

CW makes the drive more sensitive.

Normal setting is at about mid-range (50%) of pot rotation.


MCL

Current Limit

ANALOG and DIGITAL modes.

Motoring

Sets the maximum motoring current to the motor in percent of full load.

This adjustment depends on the HP calibration resistor on TB3-1 and TB3-3.

CCW is zero percent, or zero current.

CW is maximum current limit, or about 150% of full load.

In normal operation, CLIM is set to 150% (CW).


RCL

Current Limit

ANALOG and DIGITAL modes.

Regeneration

Sets the maximum regenerative current to the motor in percent of full load.

This adjustment depends on the HP calibration resistor on TB3-1 and TB3-3.

CCW is zero percent, or zero current.

CW is maximum current limit, or about 150% of full load.

In normal operation, CLIM is set to 150% (CW).
