5 Connectors and Functions
5.1 Power Supply
5.1.1 Introduction
The Motor Control board can be supplied in two ways:
§
§
Note: on the J3 connector, polarity of DC or AC input is not important.
Single power supply (for motors requiring a voltage greater than
18 V).
Power is supplied to the J3 connector. Power supply voltage must not
be higher than 42 V DC or 30 Veff AC. This power supplies both the
motor and the Motor Control board. A 15 V DC voltage is automatically
generated for the Motor Control board logic. However, depending on
the voltage supplied to the J3 connector, two cases are possible:
1.
2.
Dual power supply (for motors requiring a voltage less than 18 V).
Power for the motor is supplied to the J3 connector, while a separate
power for the Motor Control board logic must be supplied to the J1
connector (15 V DC, 0.5 A). The S1 jumper must be removed.
If the supplied voltage is greater than 35 V DC, the S1 jumper must
select the “HIGH VOLTAGE” position;
If the supplied voltage is between 18 V and 35 V DC, the S1
jumper must select the “<35V ONLY” position.
