SPA2-2 system components
A number of kits exist which contain the necessary components required to connect the SPA2-2 onto a CMM.
Motor connectors
There are two types of motor connectors:
- dc brushed motor connectors
- ac brushless motor connectors
Ensure the kit contains the appropriate connector for the installation.
Each of the three connector assemblies consist of the following:
- 1 off metal backshell
- 1 off 7W2 power and signal 'D' type plug
- 2 off power pins
Emergency stop and reset switch (supplied)
NOTE: The emergency stop function of the SPA2-2 can be used as part of a Performance Level B system as per EN ISO13849-1:2015 (or current version).
To meet a higher performance level an external safety system must be fitted.
Each kit contains one 9-way D-type socket that permits the installer to add additional emergency stop devices to the emergency stop system integrated within the SPA2-2.
This connector is of the solder bucket variety. It is recommended that they are fitted to the CMM wiring by a competent technician or engineer, and that sleeving is used for all connections to reduce the possibility of short circuits.
The SPA2-2 range of products is capable of being configured to enable support of a wide range of motor and tacho feedback giving compatibility with most machine constructions.

SPA2-2 4th axis interface card kit
This kit contains the optional 4th axis interface card for the SPA2-2 system. This permits connection of an additional machine axis to the SPA2-2 when using the UCC2 or UCC BI controller.
NOTE: Each SPA2-2 unit can only support one 4th axis interface card.
This kit contains the following components:
- 1 off 4th axis interface card
- 1 off internal connection signal loom
- 1 off internal connection power loom
- 4th axis hardware mounting kit
- 1 off mating motor connector for machine wiring
Dual SPA2-2 integration kit
This cable kit is designed to permit a high power solution for CMM installations where the power capacity of a single SPA2-2 will not address the requirements for the machine.
This system enables two SPA2-2 units to be combined as a single system and configured to drive the CMM installation. For example; if required, a single SPA2-2 can power a single axis, or if in a dual drive configuration the two dual axis motors can be supplied from separate SPA2-2 units and the other two axes to be integrated such that each SPA2-2 drives two motors.

SPA2-2 comms connection
The comms link between the UCC BI and the SPA2-2 is made using two RJ45 cables (P-CA82-0017) provided in the SPA2-2 kit.
- The UCC BI port SPA-A should be connected to the SPA2-2 port SPA-A
- The UCC BI port SPA-B should be connected to the SPA2-2 port SPA-B
If the provided RJ45 cables are not used then the cables should be no longer than 400 mm in length, CAT 5E and shielded.
Dual UCC BI interconnection
Dual UCC BI installations require a special E-STOP cable (part number A-5208-0011). This cable has three tails, all marked with their function, and must be installed as per the diagram below.
MCU, RS232, PICS, servo power amplifier / E-STOP cable and machine I/O should be connected to UCC BI 1.
UCC BI to SPA2-2
NOTE: The connection between the UCC BI's servo power amplifier socket and the SPA2-2's controller E-STOP plug is made by cable A-5121-0062. This cable is provided with the SPA2-2 (A-5402-8300).
