IMPORTANT NOTICE
If, after powering the unit, closing the run contact and sending the speed reference, the motor does
not start, check that the power circuit supply at term. 23-24 has the SAME PHASE of the control
circuit supply at term. 25-26.
If no transformer is installed on the power section, with power circuit on (remote control switch
closed, if any), check that an alternating voltage is present with a zero effective value (200mV)
between terminals 23 and 25, and between terminals 24 and 26.
STANDARD CONFIGURATION
If no custom configuration is required, the standard configuration of the AMS90/1 drive
is the following:
CONTROL SECTION POWER SUPPLY: 400Vac ±15% / 50Hz (jumper J2→pos. 400).
POWER SECTION POWER SUPPLY: 400Vac max/50Hz.
TACHO GENERATOR FEEDBACK: 180VDC max.
CURRENT LIMIT: rated value.
WARNING: before powering the unit on, check that the voltage (TR3, J2) and
frequency (*) values on the plate match those of the supply mains at terminals 25-26.
(*) Since December 2006, ES719 control board has been replaced by ES886
control board.
On ES719 board rated mains frequency is set by dip-switch SW1, while on
ES886 board it is set by jumper J6.

Note: to have the drive match the standards concerning radio-frequency immunity characteristics, keep 0V
of the board (term. 1-3-19) insulated from earth.
In turn, connect cable shield to the earth, through a connection that should be as short as possible.
Always fit a NO auxiliary contact of KM remote control switch at terminal
18, as closure of KM remote control switch AFTER closure of RUN contact, if control
section is already supplied at terminal 25-26, may destroy internal power module.

WARNING: The use of ultrafast fuses FU1/2 is recommended to protect the internal
power module in case of undesired external short -circuits. Comply with the max.
prescribed value for I2t.
NOTE: The supply voltage given above for each model is the nominal value for the
control section(±15% tolerance), whilst it is the maximum value for the power section.
The two voltage values may be different provided that they are in phase with each
other.
The L1 switching impedance is 35A/150H
(ENERTRONICA SANTERNO S.P.A. Part Number: IM0100354).
The current FF form factor can be obtained by measuring the effective value
  ae
I
of the
alternate component of the current absorbed by the motor (with a A.C. instrument with
real effective value) and the mean value Imof the same current (with a D.C. instrument).
The result is given by the following formula:
 

FF 22  
Since the motor and drive heating, as well as the periodical maintenance operations on
brushes and manifold, depend on the form factor, apply the levelling inductance L2 so
as to keep the form factor value as close as possible to 1.
Through the following formula, you can get the L2 mH value of the levelling inductance
to be inserted, assuming the motor one is negligible, using the desired form factor FF
value, the supply alternate voltage Vavalue and the mean output current Imvalue:
