1. Connect the motor armature and field leads to produce proper
direction of motor rotation. Figure 2.12 shows the connections
required to produce counterclockwise rotation of the motor
when viewed from the commutator end with a positive speed
reference input to the Drive.

*If Used
(1) In cases where full regenerative torque capability is required for braking or slow down operation or where the drive
will be applied for bi–directional operation, you should specify straight shunt DC motors (wound without a series field winding)
to assure symmetrical motor operation in both forward and reverse directions, full torque capability, and motor stability under
any mode of operation.
(2) If this connection of the motor armature leads results in motor rotation opposite of what is required, reverse the A1 and A2
lead connections at the motor.
(3) Connect Drive Terminal A2/S1 or S2 to motor terminal A2.

2. The 1397 is supplied with semi conductor fuses for line
protection. An isolation transformer can also be used. In
general, the 1397 is suitable for direct connection to a correct
voltage AC line that has minimum impedance of 3%. If the
