Modulo
Function description 53
Version: 1.5
P-0-0276 – „Modulo calculation control“
This IDN can be used to select whether the offset required for the modulo calculation is to be stored
cyclically in the drive, and in a fail-safe manner.
„0: Modulo data storage enabled“:
This setting requires a multi-turn encoder, otherwise the necessary memory operations cannot be performed
fast enough. Thanks to the fail-safe storage of data, the modulo position can be reconstructed
unambiguously after the drive was switched off and back on again, provided the encoder position was not
changed by more than ¼ of the absolute range during the off state.
„1: Modulo data storage disabled“:
With this setting, no data are stored in the drive. It enables activation of the modulo calculation even for
feedback systems that only provide a single-turn position. However, after the drive is switched off and on
again, the modulo position cannot be reconstructed unambiguously, so that homing of the axis is necessary.
The further procedure is described in the section Configuration

11.3.2 Influenced IDNs
S-0-0047 – “Pos command value”
The setpoint position is transmitted by the controller to the AX5000 as the modulo position and calculated
back into an absolute position in the range 0---2
32
-1 inc. in the AX5000.
S-0-0048 “Additive pos command value”
The additional setpoint position is transmitted by the controller to the AX5000 as the modulo position.
S-0-0051 “Pos feedback value 1 (motor feedback)”
The current actual position is calculated by the AX5000 from the position of the feedback system and the
current modulo data and is output as the actual modulo position (first feedback system).
S-0-0053 “Pos feedback value 2 (external feedback)”
The current actual position is calculated by the AX5000 from the position of the feedback system and the
current modulo data and is output as the actual modulo position (second feedback system).
S-0-0076 “Position data scaling type”
This is set by the TCDriveManager on activating the modulo function. “Processing format” = 1 enables the
modulo function.
S-0-0091 “Bipolar velocity limit value”
Maximum possible speed (see below).
S-0-0103 “Modulo Value”
Defines the modulo range. Is defined in the TCDriveManager.
S-0-0130 “Probe value 1 positive edge”
Position value from the probe unit; this is converted in the same way as the actual value.
