J2 and J3 Grounds
The ground terminals at J2-1 and J3-5 also connect to the amplifier chassis.
Motor cases can be safety-grounded either at the motor, by earthing the frame, or by a grounding
conductor in the motor cable that connects to J2-1. This conductor should be of the same gauge
as the other motor phase conductors.
The case of the regen resistor can also be safety-grounded by earthing the case or by a
grounding conductor connected to J3-5. Again, this conductor should be of the same gauge as the
other regen resistor conductors.
Cable shields, because of their smaller wire size, must not be used as part of a safety-ground
system.
Signal Grounding
The amplifier signal ground must be connected to the control system signal ground. The amplifier
signal ground is not connected to earth ground internal to the amplifier. Therefore, the control
system signal ground can be connected to earth ground without introducing a ground loop.
Shielding
Shields on cables reduce emissions from the amplifier and help protect internal circuits from
interference due to external sources of electrical noise. The shields shown in the wiring diagrams
are also required for CE compliance. Cable shields should be tied at both ends to earth or chassis
ground. The housing and pin 1 of both J7 and J8 are connected to the amplifier’s chassis.
