See FDR_Period description below for more information.
Voltage setpoint slew-rate-limit. 1.0 = nominal voltage (60V / 40V) per ms voltage setpoint rate-of-change
limit.
Current setpoint slew-rate-limit. 1.0 = nominal current of one module (167A / 250A) per ms current setpoint
rate-of-change limit.
Alpha coefficient of the low pass filter for the monitor readbacks. Normalized (0 to 0.9999).
Used for impedance calculation. If setpoints change more than this value the impedance measurement is
considered not valid. Percent per ms.
Used for impedance calculation. Time delay after the impedance calculation is considered valid again. 1 is
equivalent to 8 ms of delay

39
Z_delay
Int16
40
Modbus_timeout_period
Int16

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.
