PARAMETERS DESCRIPTION
Setpoint Local (SL) :
Corresponds to the value required for the internal regulation loop of the unit.
Authorised value between 0 and 255.
Fast Setpoint Transfer (FS) :
Used to store prepared in advance setpoints in live memory.
The setpoint is transferred to the active setpoint (address 01) by
sending code 05 in the command word.
High Setpoint Limit (HS) :
Sets the maximum value of the digital setpoint.
Authorised value between 0 and 255, stored in permanent memory.
Current Limit (CL) :
Allows nominal current calibration.
This recalibration (LS parameter) is equal to the product between the digital current (CL
parameter) and the front panel current limitation (Ilim, LL parameter).
Authorised value between 0 and 255, stored in permanent memory.
Only writable for units with the U*I option.
Optional Status word (OS) :
This parameter allows the modification of some of the product configuration bit, at the same
time and without using the Command Word CW and its codes.
Parameter stored in permanent memory.
Note :
If the configuration loaded using the Optional Status Word OS,
is not available, the only way to verify the effective result, is to read the
Status Word SW.
