25, 26 Zalpha_HI/LO IQ24 / FP Alpha coefficient of the low pass filter for all impedance calculations. Normalized (0 to 0.9999). 3
27 Save_Defaults binary 0x1234 stores current state as default, 0x5678 restores saved default, 0x9ABC restores factory defaults.
28 Query_Module binary Used to query module data, in combination with Read registers 29, 30 (Query_Module_Info).
29 Expected_Modules Int16
If non-zero a fault will be generated when existing modules does not match this value. See user guide for
more details.
30 FDR_Period Int16 See FDR_Period description below for more information.
31, 32 Vsetpoint_SRL_HI/LO IQ15 / FP
Voltage setpoint slew-rate-limit. 1.0 = nominal voltage (60V / 40V) per ms voltage setpoint rate-of-change
limit.
2, 3
33, 34 Isetpoint_SRL_HI/LO IQ15 / FP
Current setpoint slew-rate-limit. 1.0 = nominal current of one module (167A / 250A) per ms current setpoint
rate-of-change limit.
2, 3
35, 36 monitor_alpha_HI/LO IQ24 / FP Alpha coefficient of the low pass filter for the monitor readbacks. Normalized (0 to 0.9999). 2, 3
37, 37 max_delta_setpoint_HI/LO IQ15 / FP
Used for impedance calculation. If setpoints change more than this value the impedance measurement is
considered not valid. Percent per ms.
2, 3
39 Z_delay Int16
Used for impedance calculation. Time delay after the impedance calculation is considered valid again. 1 is
equivalent to 8 ms of delay
40 Modbus_timeout_period Int16 Used with Modbus timeout feature. 1 is equivalent to 8 ms of delay
41, 42 activation_code_HI/LO Int32
Code to unlock the digital interface. A value of all ones ( 4294967295) will lock it. The correct unlock code
is based on an encryption algorithm and the Master Controller serial number.
