Description

0 Standard mode. Encoder-based sinusoidal commutation for brushless motors. Use digital

Hall inputs to initialize phase, then switch to an encoder to maintain phase. The encoder is

the primary sensing device with the Hall effect sensors used to monitor and adjust the phase

angle as necessary during operation.

1 Trapezoidal (Hall based) phasing. The Hall sensors are used for phasing all the time. This

mode can be used if no encoder is available.

Like mode 0 except that the phase angle is not adjusted based on the Hall inputs. Hall

sensors are still required to initialize the phase angle at startup.

Analog Halls (90 degrees). Only available on drives with the necessary analog Hall inputs.

DC brush motor mode.

Algorithmic Phase Initialization mode (wake & wiggle, no Halls).

See the CME 2 User Guide for more information on Algorithmic Phase Initialization.

Encoder based phasing. Use with resolver or Servo-Tube motors.

Trapezoidal commutation with phase angle interpolation.

INT16

Analog Encoder Scaling Factor. This parameter selects the resolution of an analog

encoder input. The parameter is not used for other encoder types.

INT16

Encoder Phase Angle. For feedback types, such as resolver, that can also calculate

phase angle information. This parameter allows the phase information to be read

directly.

INT32

Homing Adjustment. This parameter is updated after each successful homing

operation. The value it contains is the size of the actual position adjustment made in

the last home sequence. Units: counts.

U16

PWM Input Frequency. This is the frequency of the PWM for use in UV commutation

mode only. Units: 10 Hz. This parameter is also used to specify an optional PWM

dead band when running in normal (not UV) PWM command modes. When used as

a dead band value, this input should be set in the range 0 to 32767 which

corresponds to a dead band of 0 to 100% of the PWM duty cycle.

INT32

Positive Software Limit. This parameter is only available on drives that support

trajectory generation and homing. Software limits are only in effect after the drive has

been referenced (i.e. homing has been successfully completed). Set to less than

negative software limit to disable. Units: counts.
