JP solder bridges
Standard
bridges
In the “ADJUSTMENT ZONE” there are
ten solder bridges;with these we can
enable or disable functions or 3.005.4
circuit sections.
They allow obtain different ACC/DEC times.
(see chapter 4.3 calibration)
Normally closed. If it is open loop standard costants
CKI-RKI are disabled.
Normally closed. If it is open current loop standard
costants CKV-RKV are disabled.
Normally closed. If it is open velocity loop static
gain is disabled.
Normally open . If it is close the armature feedback is
enabled.
Normally closed. We open this when we wish to drive
the amplifier with external current reference.(velocity
loop disabled)
Normally open. If it is closed,thermic image IxT circuit
activation donʼt stop the output transistor and the green
led light.(Drive ok)
Normally close.If it is opened ,lost or reverse tacho
circuit activation donʼt stop the driver working.
It must be opened when armature feedback is used.
In the amplifier thereʼs a tachogenerator protection that prevent motor runaway.
If we insert a wrong RDT resistance tachogenerator fault donʼt intervent.
Please verify the correspondance of solder bridge closing point referred to needed function
of driver .
These are the solder bridges(see page 10) normally closed and open supplied as standard

Attention at the power supply polarity !!
Verify all screw clamp connections and double check on
driver wiring following motor and tacho polarity we will obtain
clockwise direction with positive speed reference.
After the preliminary checks we can insert the amplifier on the mother-board
the motorʼs shaft must be free from the load be ready to stop main supply net if will be
necessary after. Disable PWM ON.
Put power on driver.Green light led will be on normally if not on ,please verify with a tester
voltage value ;” min or max voltage protection on” .
With analogue input on zero level abilitate PWM on.If motor stays with torque or turns
very low,tacho polarity is ok.
If tacho polarity is inverted ,after a little rotation MD protection”tacho loss inverted polarity”
is activated and it stops the driver (obviously if also JP 10 bridge is closed).
The alarm is shown with red led light on (not resettable protection)shut power circuit ,reverse
tacho cables and start on again.
For further malfunctions,see chapter “fault research”.
