KANZ series servo motor with premade cables
This article gives tips for fast-forward installation of KANZ series Granite Devices servo motors on Argon servo drive. However, this article is not complete user guide for Argon, so user must be already familiar with operation of the drive or follow Argon user guide simultaneously.

Wiring

Wire preparation

KANZ motors come with pre-assembled cables for Argon servo drive (encoder and motor part). However, some motor models include excessive 4-pin terminal for motor part that needs to be stripped away.

  • The excessive 4-pin connector that need to be cut away. Stripping 3-5 cm of black outer insulation is recommended to make space for EMI suppression cores.

  • Strip wire ends. Cutting U,V,W 1-2 cm shorter than PE is recommended for safety (to make PE the last to disconnect if cable pulled by force).

  • Optional, but recommended, ferrule crimping of wire ends.

  • Minimum length of wire ends to fit single EMI suppression core to leads. Note: it recommended to strip outer insulation before crimping.

Ensure that insulation of inner wires have not been damaged in the process of wire stripping and termination and that there is no loose wire strands

Connecting

Pre-made encoder cable plugs directly into Argon J1 connector and motor U, V, W and PE connect to J4 terminal to their respective positions. Insert EMI suppression cores as illustrated below:

Parameterization

For parameterization, make sure you understand Argon drive parameterization basics. To speed up commissioning of motor, pre-made base configuration files are provided for stocked servo motors. Instructions for using the files:

When loading settings, have drive disconnected from AC power for safety reasons. Ensure that all settings and wirings (including emergency stopping) are ready before connecting AC power.
  1. Download KANZ motor configuration files: Media:KANZ Argon base settings.zip
  2. Connect drive to Granity (instructions)
  3. Click Load settings from file and open corresponding configuration file. Choose the file that is most has similar beginning with motor mode (i.e. KANZ04... file for KANZ-04BF8N2 motor).
  4. Click Save settings on drive non-volatile memory and if choose Apply and Restart drive buttons in the dialogs that may appear
  5. After drive restarts, connect again to drive and review all settings. For first testing safety it is recommended to reduce current limits MMC and MCC to a lower value (such as 20% of rated values) in order to limit motor torque if unexpected motion takes place. Also set control mode CM as required by end application.
  6. After all Ok, click Apply settings and you're ready to connect AC power for first tests.
  7. Go to Testing page and begin motor tuning according to Servo motor tuning guide
Pre-made motor configuration files may have significantly different motor resistance MR and inductance ML values compared to motor data sheet. Pre-made files are hand-optimized to give better performance than entering values from data sheet, so it is recommended to leave these values untouched.
