2.1.2RS485 / RS422 systems

If your PC does not have an RS485 / RS422 connector, an RS232 to 4-wire RS485 / RS422 converter will be required. This allows signals from the RS232 port to be converted to the signals necessary for RS485 / RS422 communications. Appropriate converters are available from KK Systems Ltd (www.kksystems.com).

Note: If this is the first time you are installing a MintDrive then it is strongly recommended that you use RS232 to get started and use RS485 later. This will avoid any potential problems involving the RS232-RS485 converter.

Also, MME (Mint Motion Engine) firmware can only be updated over RS232.

2.1.3Power sources

If the MintDrive requires an external 24VDC for the logic supply then this must be a regulated power supply with a minimum current supply capability of 1.6A. A 24V filter may be required to comply with the CE directive for which the MintDrive was tested (see page 18).

A 24VDC power supply is required for the drive enable input, the digital outputs and the digital inputs; 24V cannot be sourced from the MintDrive unit itself.

A mains source (installation over-voltage category III or less) in the installation area is required. This will need to be single or three phase depending upon the type of MintDrive. A mains filter is required to comply with the CE directive for which the MintDrive was tested (see page 18).

2.1.4Tools and miscellaneous hardware

H Your PC operating system user manual might be useful if you are not familiar with Windows H A small screwdriver with a blade width less than 1/8” (3.5mm)

H Screws or bolts (depending on your own mounting requirements) with an M5 fixing H Soldering equipment with suitable soldering tips.

2.1.5Other information needed for installation

You will need the following information to complete the installation:

HThe data sheet or manual provided with your motor, describing the wiring information of the motor cables/connectors

HWhether digital inputs/outputs will be ’Active Low’ or ’Active High’ to meet the requirements and specification of the system you are going to build.
