Setting the motor data

Prior to commissioning, the motor controller requires a number of values from the motor data sheet.

  • Number of pole pairs: Object 2030h:00h (pole pair count) The number of motor pole pairs is to be entered here. With a stepper motor, the number of pole pairs is calculated using the step angle, e.g., 1.8° = 50 pole pairs, 0.9° = 100 pole pairs (see step angle in motor data sheet). With BLDC motors, the number of pole pairs is specified directly in the motor data sheet.
  • Object 2031h:00h: maximum permissible motor current (motor protection) in mA (see motor data sheet)
  • Object 6075h:00h: rated current of the motor in mA (see motor data sheet)
  • Object 6073h:00h: maximum current (for a stepper motor, generally corresponds to the rated current, bipolar) in tenths of a percent of the set rated current (see motor data sheet). Factory setting: "1000", which corresponds to 100%.
  • Object 203Bh:02h Maximum duration of the maximum current (6073h) in ms (for initial commissioning, Nanotec recommends a value of 100 ms; this value is to be adapted later to the specific application).
  • Setting the motor type:
    • Stepper motor:
      • Object 3202h:00h (Motor Drive Submode Select): Defines motor type stepper motor, activates current reduction on motor standstill: 0000008h.See also chapter Commissioning open loop.
    • BLDC motor:
      • Object 3202h:00h (Motor Drive Submode Select): Defines motor type BLDC: 00000041h
  • Motor with encoder: Object 2059h:00h (Encoder Configuration): Depending on the encoder version, one of the following values is to be entered (see motor data sheet):
    • Supply voltage 5V, differential: 00000000h
    • Supply voltage 5V, single-ended: 00000002h
  • Motor with brake: Object 3202h:00h (Motor Drive Submode Select): The brake control is activated for the initial commissioning. Depending on the specific application, this configuration can be deactivated later if necessary. One of the following values is to be entered depending on the motor type:
    • Stepper motor, brake control (and current reduction) activated: 0000000Ch
    • BLDC motor, brake control activated: 00000044h
