IDN 76 (S-0-0076) Position Data Scaling Type

Defines the scaling options for all position data. The supported scaling types are indicated in bold-face type. The following scaling types are available: 0001(Hex), 0081(Hex), 0009(Hex), 0089(Hex), 000A(Hex) and 008A(Hex).

If linear scaling is selected without modulo format on (bit 7 = 1), the software limit switches are automatic switched on (refer to IDN 49 , 50, 55 and IDN 3004 ).

If modulo format is selected, the drive operates without interpolation.

If rotational scaling is selected and the rotational position resolution ( IDN 79 ) is different from 1048576 or 65536 the modulo format must switch on, this will check during run up. A change of bit 7 will initiate a warm start procedure (refer to IDN 128 during run up. With set the operation mode within IDN 32 or 33 to position control with external feedback, this IDN will set to 004A(Hex) as a fixed setting. The drive can only operate with a fixed rotational scaling for the position data in this case (refer to IDN 79 ).
