39.DIGITAL OUTPUT #2 FUNCTION

USE PARAMETER #39 TO SELECT THE #2 DIGITAL OUTPUT FUNCTION.

RANGE OF VALUES: 0000 0000h to 0001 000Fh no decimal significance

Default Value: 0000 0001h no decimal significance

The setting options are the same as parameter #38. The default, by factory setting, is 0000 0001h, which is the FAULT output. The internal FAULT circuitry of the DFS-1 is off when the input power is applied and energizes if there are NO FAULTS in the drive (the contact closes because VL1 is set to 01h).

40.DIGITAL OUTPUT #3 FUNCTION

USE PARAMETER #40 TO SELECT THE #3 DIGITAL OUTPUT FUNCTION.

RANGE OF VALUES: 0000 0000h to 0001 000Fh no decimal significance

Default Value: 0001 0002h no decimal significance

The setting options are the same as parameter #38. The default, by factory setting, is 0001 0002h, which is the AT SPEED output. The internal AT SPEED circuitry of the DFS-1 is on when the actual speed of the motor matches the commanded speed (the contact closes because VL3 is set to 01). There are no AT SPEED window parameters because the microprocessor filters and averages the speed signal.

41.DIGITAL OUTPUT #4 FUNCTION

USE PARAMETER #41 TO SELECT THE #4 DIGITAL OUTPUT FUNCTION.

RANGE OF VALUES: 0000 0000h to 0001 000Fh no decimal significance

Default Value: 0001 0003h no decimal significance

The setting options are the same as parameter #38. The default, by factory setting, is 0001 0003h,

which is the REMOTE output. When the DFS-1 is in the remote mode, the contact between the terminals closes (the contact closes because VL3 is set to 01h).

42.DRIVE GAIN SETTING

USE PARAMETER #42 TO SET THE INTERNAL CURRENT GAIN OF THE DRIVE.

RANGE OF VALUES: 0000 0000h to 0000 00FFh

0 to 255

(decimal)

Default Value: 0000 0080h

128 (decimal)

The gain of the DFS-1 is set by parameter #42. The effect of the gain setting is to adjust an internal value which determines how many pulses of accumu- lated shaft position error it takes to reach current limit. A 00h will allow about 90 pulses of position error while a setting of FFh allows only about 9 pulses, which makes the motor shaft very “stiff”, in that turning it only a few degrees causes current to increase very rapidly. A middle setting is the default.

43.DRIVE STABILITY SETTING

USE PARAMETER #43 TO SET THE INTEGRAL CURRENT GAIN OF THE DRIVE.

RANGE OF VALUES: 0000 0000h to 0000 00FFh

0 to 255

(decimal)

Default Value: 0000 0080h

128 (decimal)

The stability of the DFS-1 is set by parameter #43. The effect of the setting is to adjust an internal value which controls the integral and differential gains of the drive. Smaller numbers mean faster reaction to changes and for higher numbers reaction is more damped. A middle setting is the default.

44.DRIVE MOTORING CURRENT LIMIT

USE PARAMETER #44 TO SET THE MOTORING CURRENT LIMIT OF THE DRIVE.

RANGE OF VALUES: 0000 0000h to 0000 0096h 0 to 150% (decimal)

Default Value: 0000 0032h

50% (decimal)

Parameter #44 allows current limit settings of up to 150% and must be set in terms of MOTOR current. Other circuitry in the motor control will
