RSAP (restore axis parameter)
For all configuration-related axis parameters non-volatile memory locations are provided. By default, most
parameters are automatically restored after power up (refer to axis parameter list in chapter 6). A single
parameter that has been changed before can be reset by this instruction also.
Internal function:
The specified parameter is copied from the configuration EEPROM memory to its RAM
location.
Relate commands:
SAP, STAP, GAP, and AAP
Mnemonic:
RSAP <parameter number>, 0
Binary representation:
INSTRUCTION NO.

List of parameters, which can be used for RSAP:
Number Axis Parameter
Description
4
maximum
positioning
speed
Should not exceed the physically highest
possible value. Adjust the pulse divisor (no.
154), if the speed value is very low (<50) or
above the upper limit.
5
maximum
acceleration
The limit for acceleration (and deceleration).
Changing
this
parameter
requires
re-
calculation of the acceleration factor (no. 146)
and the acceleration divisor (no. 137), which is
done automatically.
6
absolute max.
current (CS /
Current Scale)
The most important motor setting, since too
high values might cause motor damage!
The maximum value is 255. This value means
100% of the maximum current of the module.
The current adjustment is within the range 0…
255 and can be adjusted in 32 steps (0… 255
divided by eight; e.g. step 0 = 0… 7, step 1 =
8… 15 and so on).
7
standby current
The current limit two seconds after the motor
has stopped.
