The available ramp regulations depend to the driver version:
- in the standard version it is available a single regulation for rise/fall ramp (P7)
- in the /RR version it is possible to separately regulate the rise ramp and the fall ramp (P7 and
P17)
In the version /4R-4 it is possible to separately regulate the ramp for each of the internal reference
signals (P11-P12-P13-P14).
External ramps, see
This feature allows to regulate the ramp time by means of external potentiometers. In order to use
this capability:
- set switch SW1 in position 2
- connect one or more external potentiometers as shown (use only 2,5 MΩ potentiometers).
Internal reference signals
In the version -4, /RR-4 and /4R-4 the driver can self generate 4 different internal reference signals,
selectable by means of 4 relevant on-off commands 24 V
DC, to be supplied to the contacts 22c,
24c, 24a, 22a (see scheme
,
): each internal reference signal can be adjusted by means of a
relevant potentiometer available on the front panel.

7 INSTALLATION AND START-UP
It is advisable to perform calibration procedures in the order given below.
7.1 Warning
– Never insert or remove the driver while the electronic system is powered on.
– Voltages must always be measured with reference to GND (connector contact 8a or front panel
test point ).
– Refer to to identify components mentioned in calibration procedures.
7.2 Start-up
Factory pre-set adjustments might not meet the desired requirements for the specific application
and performances can be optimized by on-site re-adjustements of Bias, scale and ramps potentio-
meters, in sequence.
– Connect the electronic driver according to the desired connection diagram,
,
.
The current supplied to the coil can be measured by a voltmeter connected between the test
points on the front panel.
For E-ME-AC-05F the channel enabled led (L5 or L6) shows the supplied coil.
Enabling signal, see ,
.
The electronic driver operate when the contact 18a is supplied with an enabling signal (usually
24V
DC
). It could be useful in emergency conditions to inhibit the driver by zeroing this signal.
Bias adjustment (Dead band compensation), see
, , .
– Supply a reference signal voltage (0V
DC
for E-ME-AC-01F and ± 0,1V
DC
for E-ME-AC-05F).
Gradually turn bias potentiometer(s) until a movement of the controlled actuator is obtained
– Turn in the opposite direction until the actuator is stopped.
Scale adjustment, see
, , .
Supply max reference voltage signal (for E-ME-AC-05F driver repeat for max negative voltage) in
the specified range and turn scale potentiometer(s) until the actuator speed reaches the desired
value.
Ramps, see , .
Turning the ramp potentiometer(s) clockwise, acceleration(s) and deceleration(s) can be reduced
to obtain optimization of the complete system.
