Axis Parameters
The following sections describe all axis parameters that can be used with the SAP, GAP, AAP, STAP and
RSAP commands.
Attention!
Related to positioning, there are parameters which have two unit specifications.
- In
open loop mode
, calculate with
µsteps
.
- In closed loop mode, calculate with encoder steps.
For further information about closed loop operation parameters and functions please refer to Section 9.

W
SAP, AAP
Parameter writable
E
STAP, RSAP
Parameter automatically restored from EEPROM after reset or power-on. These
parameters can be stored permanently in EEPROM using STAP command and
also explicitly restored (copied back from EEPROM into RAM) using RSAP.
Basic parameters should be adjusted to motor / application for proper module operation.
Parameters for the more experienced user

please do not change unless you are absolutely
sure!

Target speed
The desired speed in velocity mode (see ramp

In position mode, this parameter is set by
hardware:
-
during acceleration to maximum speed
-
during deceleration and rest to zero
