ADJUSTMENTS
CCW = Counter-ClockWise position CW = ClockWise position
MIN Minimum Speed ANALOG MODE only.
No effect unless speed pot is connected to TB2-11.
Effect equals 100 * 1000/(Speed Pot Value + 1000) percent of full speed
CCW is 0% effect, or zero speed.
CW is full effect. With a 5000 ohm speed pot, this is 16% of full speed.
MAX 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 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.
ACCEL Acceleration time ANALOG MODE only.
Sets amount of time to change from zero speed to full speed.
With JP2 installed, CCW is about 90 seconds.
With JP2 not installed, CCW is about 2 seconds.
With JP2 installed, CW is about 2 seconds.
With JP2 not installed, CW is about 0.05 seconds.
DECEL Acceleration time ANALOG MODE only.
Sets amount of time to change from full speed to zero speed.
With JP2 installed, CCW is about 90 seconds.
With JP2 not installed, CCW is about 2 seconds.
With JP2 installed, CW is about 2 seconds.
With JP2 not installed, CW 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.
CLIM Current Limit ANALOG and DIGITAL modes.
Sets the maximum average 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.
Initial startup should be made with CLIM fully CCW.
Increase CLIM to full CW gradually as confidence in setup is gained.
In normal operation, CLIM is set to 150% (CW).
