DANGER OF ELECTRICAL SHOCK
ONLY QUALIFIED PERSONNEL SHOULD WORK ON THIS EQUIPMENT. DISCONNECT ALL POWER
BEFORE WORKING ON EQUIPMENT. DANGEROUS VOLTAGES MAY EXIST AFTER POWER IS
REMOVED! BEFORE WORKING ON EQUIPMENT CHECK DC BUS VOLTAGE OF
DRIVES EACH TIME POWER IS REMOVED.
The transformer power is
P=Vac*(Inf(tot) + 1)
Where
P is VA power, Vac is secondary voltage in Volts and Inf(tot) is the sum of all nominal currents set
in all
the drive to be supplied.
NOTE: use a transformer with an isolated secondary, don’t connect the secondary at ground.
Vac nom :
Range value of voltage by which the drive can be powered.
Vac max:
Opertative Maximum voltage. Over this limit, the protection of maximum voltage inhibits the
drive.
Vac min:
Operative Minimum voltage. Under this limit, the protection of minimum voltage inhibits the
drive.
I max:
Maximum value of phase current.
I min:
Minimum value of phase current.
Operating temperature:
For any temperature over 45°C and any current over 6A a forced ventilation is
necessary.
Vdc aux
: Logic power supply.
