ST System Wiring Diagram Notes
Note 1
Resistor is connected to high voltage. Please ensure sufficient electrical clearance when
mounting. Resistor may become very hot during operation. Do not mount near materials that
are flammable or damaged by heat. Ventilation may be required. Each kit has different
series/parallel resistor connectors to obtain specific resistance and power rating. For guidance
on application sizing of Regen Kits, see Application Note, SERVOSTAR S/C-Series
Regeneration Requirements on the PSP CD-ROM, or the Kollmorgen website
(www.MotionVillage.com) and Kit Parts and Models on page 13 for more details.
When using internal regen, leave jumper installed between terminals "R" and "C". Remove
Note 2
when using external regen kit.
A thermal overload relay is supplied in the regen resistor kit. The thermal overload relay was
Note 3
sized for the resistance and power rating of the resistor. The output contacts of the relay must
be wired to drop power to the main power contactor during a fault condition, as shown in the
drawing. Do not wire Logic Control power through the main power contactor. Control power
should not be removed if BUS module's fault contacts open as this resets fault LEDs.
The fault contacts must be wired in series with the overload relay as shown in the drawing.
Note 4
This contact is normally open and will close after application of control and main power. This
contact opens in fault conditions. See BUS Electrical Specifications on page 12.
* Attempting to enable the drive before this BUS OK becomes active may cause BUS module
to remain inactive.
Transformer may be omitted if correct voltage source is applied. See BUS Electrical
Note 5
Specifications on page 12 for correct line input.
The ground of the BUS module, drive, and motor best minimizes ground currents and noise
Note 6
when connected in a "star point" configuration.
Note 7
Up to 2 drives can be supplied from a PS08 or PALM. All other power supplies can drive up
to 4 drives for logic power.
The BUS module line inputs are not phase sensitive.
Note 8
See BUS Electrical Specifications on page 12 for recommended line input fusing.
Note 9
Cables should be properly bonded to the backpanel and implemented as close to the drive side
Note 10
of the cable as possible for effective grounding. If bonding is installed, the shield on the cable
end need not be connected to the "star point" configuration. Only connect the shield on one
end of the cable; preferably on the drive side. See Installation Practices on page 21 for full
details.
Units must be installed in an enclosure that meet the environmental IP rating of the end

product ( ventilation or cooling may be necessary to prevent enclosure ambient from
exceeding 45°C).

Note 14
Control logic input can be tapped directly off the main line input. If this source is used, the
Note 15
user must recognize that if the main line power is lost, all latched fault data will be reset and
unavailable.

Note 16
Specifications on page 18 for spade and ring terminal sizes.
This system is suitable for use on a circuit capable of delivering not more than 5000 RMS
