4.0 Installing the SPA1
4.1 Preparation of SPA1 service pack
When the SPA1 service pack is received it contains all the components required to construct the following
items. These items will assist in the connection and set-up of the SPA1 unit.
4.1.1 Motor connectors
The service pack contains three motor connectors that fit the motor output from the SPA1.
Each of the three connector assemblies consist of the following:
- 1 off metal backshell
- 1 off power and signal D-type connector
- 2 off power pins
The power and signal D-type and power pins are all of the solder bucket variety and should be fitted to
the CMM wiring by a competent technician or engineer.
4.1.2 20 K potentiometer on dil header
The 20 K potentiometer on dil header must be constructed for use (if required) as detailed in section 4.5.1
step 12.
To fit a 20 K potentiometer on dil header the following procedure is recommended.
- Place the dil header on a firm surface.
- Solder two of the potentiometer legs (centre and one side) to one side of the dil header, and the other
leg to the other side, refer to figure 8 below.
Figure 8 - 20 K potentiometer on dil header
4.1.3 20 K potentiometer on 150 mm wire
The 20 K potentiometer on 150 mm wire must be constructed for use (if required) as detailed in section
4.5.1 step 3 onwards.
To construct the 20 K potentiometer on 150 mm wire the following procedure is recommended.
- Take the wire supplied in the SPA1 service pack and cut it in half.
- Solder one of the wires to two of the potentiometers legs (centre and one side).
- Solder the second wire to the other potentiometers leg.
- Solder either of the wires, with the potentiometer fitted to the other end, to pin 1 on the dil header,
refer to figure 9 below.
- Solder the other wire, with the potentiometer fitted to the other end, to pin 16 on the dil header, refer
to figure 9 below.

18 Installing the SPA1
4.1.4 Emergency stop
The service pack contains a 9-way D connector and backshell which fits the Emergency stop connector
from the SPA1.
This connector is of the solder bucket variety and should be fitted to the CMM wiring by a competent
technician or engineer.
4.1.5 Machine I/O connector
The service pack contains a 37-way D connector and backshell which connects to the cable linking the
UCC1 machine I/O connector and the SPA1 machine I/O connector.
This connector is of the solder bucket variety and should be fitted to the CMM wiring by a competent
technician or engineer.
4.2 Setting of the motor voltage
The SPA1 has the ability to drive either 24 V or 48 V motors, the factory settings for the unit is the 48 V
configuration.
The following procedure gives instructions to change the configuration of the SPA1 to permit a 24 V motor
voltage.
CAUTION
- It is essential that full anti-static precautions be taken before working within the SPA1 enclosure.
- Before the SPA1 is opened up mains power to the SPA1 must be switched off.
- The heat sink on the SPA drives could be warm to touch.
- It is essential that full anti-static precautions be taken before working within the SPA1 enclosure.
- The SPA1 unit contains components that store energy. After power has been removed the installation
engineer should wait a minimum of 30 seconds prior to working within the SPA1 enclosure.
1. Remove AC supply from SPA1 and disconnect other system cables to CMM.
2. Remove top panel of the SPA1 enclosure; ensure that all fixing screws are retained for future re-
assembly.
This is completed by removal of a screw from each side of the SPA1 unit towards the front of the
enclosure, and removal of the 5 screws across the top of the rear panel of the SPA1. Then the top of
the SPA1 can be removed by pulling upward on the lid of the unit.
