1.3 Inputs and outputs
The following numeration concerns inputs and outputs about DIN 41612 connector.
Wiring must be done on the terminal boards connections:
on mother board and on rack pc board .(see chapter 3.3 wiring).

COMMON ZERO SIGNALS
DRIVE OK (OUTPUT)
Open collector: max current(100 mA) is protected with zener diode (47 v)
Normally close on.Itʼs
DEMAND COMMAND CURRENT (INPUT OUTPUT) see page 23
It can use in two modes :
1°Current limitation :
We connect a resistance between pin 2 and pin 3 (zero)
2° Current reference : ( torque input )
We apply +/- 10 v signal, it correspond at peak current .
We can use 3 ac pin also as signal representive of the motor current.
Use instrument with impedance greater than 100 k .
- 10V (OUTPUT)
Output voltages for external use - 10 volt (max current 5 mA )
+10 V (OUTPUT)
Output voltages for external use +10 volt (max current 5 mA)
VELOCITY REFERENCE (INPUT)
Noninverting differential input +/- 10 volt
ENABLE (INPUT)
Logic signal for amplifier 10/30 vdc
VELOCITY REFERENCE (INPUT)
Inverting differential input +/- 10 volt
COMMON ZERO SIGNALS
TACHOGENERATOR (INPUT)
Input tachogenerator signal
5.1 Led's diagnostic
Led's
diagnostic
OK LED (green normally light on)
This led shows proper functioning of the
amplifier.
It switch off when is activated a whatever
protections shown also from red led light on.
It switch off when over/under voltage protection
is activated.
I.n. LED
(Red normally switch off)
When this led is lighted protection IxT is
activated, limit and max current provided is the
rated current.
This “alarm” donʼt cause the disabilitation of the
amplifier.
The amplifier return automatically to normal work
when current consuption goes to a normal value.
If the JP 9 solder bridge is closed is not activated
the interdiction of the output transistor and the
switching off of the green led (drive ok see page
10)
O.C. LED
(RED normally switch off)
Alarm of over current fault.
The power switching of the drive is continuosly monitored,and circuit will disable power
section if any of the following faults occur:
-Motor armature leads shorter
-Motor armature shorted to ground
-Motor armature shorted to power supply
This fault provoke the memorization of the alarm;can be reset by turning off the main
power for several seconds,and then turning it on again.
S.T. LED (
red normally switch off)
Alarm of over temperature fault.The power switching bridge is provided with a thermoswitch
which opens when the temperature exceeds a safe operating level.
This fault provoke the memorization of the alarm.It canʼt be reset.We must wait or a lower
heatsink temperature and then turning on the main power.
M.D.LED
(Red normally switch off)
Alarm of loss of tachogenerator signal or tachogenerator signal reverse.
This fault provoke the memorization of the alarm.
