When connecting several Ocarinas to several motors, all should be wired in an identical
manner.
Table 2-1: Connector for Main Power and Motor
2.5.1 Connecting Motor Power
2.5.1.1 Ocarina/Castanet Connected to DC Motors
To connect the Ocarina or Castanet to a DC motor, connect Hall A (J1 pin 4 of the drive) to Hall
return (J1 pin 17 of the drive). The motor should be connected to M2, M3.
2.5.1.2 Ocarina/Castanet Connected to AC Motors
Connect the motor power cable to the M1, M2 and M3 terminals of the main power connector and
the fourth wire to the PE (Protective Earth).
Notes for connecting the motor cables:
ƒ For best immunity, it is highly recommended to use a 4-wire shielded (not twisted) cable
for the motor connection. The gauge is determined by the actual current consumption of
the motor.
ƒ Connect the shield of the cable to the closest ground connection at the motor end.
