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.
NOTE: 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.
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.
NOTE: Emergency stop switches (where required by the manufacturer or installer's risk assessment) must comply with the
requirements of standards UL1054/EN60947.
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.
