References in positioning mode (with an ACSM1 drive only)

In positioning mode, references are 16-bit or 32-bit words. A 32-bit

reference contains a sign bit and a 31-bit integer. A negative

reference (indicating reversed direction of rotation) is formed by

calculating the two’s complement from the corresponding positive

reference.

For a 32-bit position reference (XSOLL_A), the unit and scaling

are defined by drive parameters (e.g. POS UNIT, POS2INT

SCALE and FEED CONST).

For a 32-bit velocity reference (VELOCITY_A), the unit and

scaling are defined by drive parameters (e.g. POS SPEED UNIT

and POS SPEED2INT).

Actual values

Actual values are 16-bit or 32-bit words containing information on

the operation of the drive. The functions to be monitored are

selected by a drive parameter.

Actual values in speed control mode

The scaling of 16-bit actual speed values (ACT or NIST_A) in

hexadecimal (0 … 4000h) corresponds to 0 … Maximum

Reference (as defined by a drive parameter).

The scaling of 32-bit actual speed values (NIST_B) in

hexadecimal (0 … 4000 0000h) corresponds to 0 … 100% of

Maximum Reference (as defined by a drive parameter).

Actual values in positioning mode (with an ACSM1 drive only)

For a 32-bit actual position value (XIST_A), the unit and scaling

are defined by drive parameters (e.g. POS UNIT, POS2INT

SCALE and FEED CONST).
