FUNCTION
RENC
Encoder resistor adjustement
RA
Armature resistor adjustement
RCA
Droop compensation for internal motor resistance (RI)
RIN
Nominal drive current resistor
RIP
Peak drive current resistor
RKV
Resistor value that respectively form the proportional/integral network of the
velocity Loop gain. Disabled by opening solder bridge S4. Standard value 100k
and 47nF.
GAIN
Changes static gain in the velocity loop. Open solder bridge S5 and insert R
GAIN if a change is required. Consult factory for the correct value.
RAMP
Resistor for change RAMP function. See Chapter 3.5
CKV
Capacitor value that respectively form the proportional/integral network of the
velocity Loop gain. Disabled by opening solder bridge S4. Standard value 100k
and 47nF.
CDER
Derivative constant capacitor, increases the velocity loop derivative constant.
Consult factory for the correct value.
SOLDER POINT
1 & 3
Normally open (OFF)
See Chapter 3.5 “Ramp time adjustment”
2
Normally closed (ON) See Chapter 3.5 “Ramp time adjustment”
4
Normally closed (ON) If Open , install components in the adjustment zone, for
the dynamic velocity value CKV and RKV. (Standard value RKV=100Kohm ,
CKV= 47nF).
5
Normally closed (ON) If Open you must insert the GAIN resistor. (Static
Gain). Standard value= 27 ohm
6
Normally open (OFF) If closed, when the IN protection operates the green
OK LED goes off.
7
Normally open (OFF) If closed the drive is set is for the armature feedback.
Insert also the resistance RA and RCA
8
Normally closed (ON) In this position the drive is set is for the encoder
feedback. If Open (OFF), are enable other type of feedback.
9
Normally open (OFF) If closed setting the drive for PWM+DIR comand
10
Normally open (OFF)
11
Normally closed (ON) If open (OFF), the alarm protection for missing Hall
Effect Signals will not disable the drive.
