GEM Drive with CANopen communication protocol for sinusodial brushless AC motors

The Gem Drive makes the interpolation between the position input commands provided by the host system as well as the synchronisation between several axes.
It is available as a stand-alone single-axis block including all supplies and mains filters or in multiaxis configuration.

The user friendly parametrization software Gem Drive Studio allows the display of all parameters as well as their easy modification. The very small dimensions of the Gem Drive allow an optimum integration in 300 mm deep cabinets (connectors included).

Main specifications

Two input voltage versions:

• 230 V_AC: 1-phase
• 400 V_AC / 480 V_AC: 3-phase

Current range (Amps):

• 230 V: 5 / 8 / 11 / 17 / 30
• 400 V: 5 / 7 / 14 / 20 / 30 / 45 / 60 / 90

2 communication interfaces:

• CAN network (CANopen protocol)
• Serial link RS-232 (or RS-422)

Automatic functions:

• Auto-tuning (automatic adjustment to the load)
• Auto-phasing (automatic adjustment to motor and resolver or encoder)

Other features:

• 16-bit resolver conversion
• Three programmable tasks (structured text)
• Servo functions integrated (gearing, camming, path generator)
• Virtual axis capability with synchro generation
• Cogging torque compensation
• Space and time filtering of the position captures
• Two analog inputs accessible via CANopen
• Four configurable PDOs
• Both resolver or encoder feedback sensors available in the drive and software selectable
• Load position feedback with the second position sensor input (not used for the motor control)
• Encoder feedback:
  • Incremental encoder (TTL or SinCos)
  • Incremental encoder (TTL or SinCos) + Hall Effect Sensors (HES)
  • Absolute single-turn SinCos encoder (Heidenhain ERN 1085 or compliant)
  • Absolute single-turn or multi-turn SinCos encoder with Hiperface or Endat protocol
• Selectable analog input
