PW[N] - PWM Signal Parameters

Purpose:

 PW[1] defines the offset value for PWM signals in fractions of the Duty cycle.

 PW[2] defines the dead band zone of the PWM signal in the fractions of the Duty cycle.

At times, the application requires the Duty cycle value to be different from the source of

the PWM signals (i.e. offset). The PW[1] parameter is intended for this purpose.

The Actual Duty Cycle is Estimated Duty Cycle - Offset

A very low Duty cycle values may cause a motor to “crawl” when a complete stop is

desired

The dead band zone parameter (PW[2]) forces the Actual Duty Cycle to zero when it is

less than PW[2].

Attributes: Type: Parameter, Real

Source: Program, RS-232, CANopen

Restrictions: None

Default values: PW[1]=0, PW[2]=0(RS), Non-volatile

Range: PW[1]: [-1.0 …1.0]

PW[2]: [0.0 …1.0]

Index range: [1, 2]

Unit modes: All

Activation: Immediate

Notes:

 A SimplIQ drive may receive the PWM signals in two formats: 50% and 100% Duty

cycle. For more details, please refer to YA[] command
