DEVICE PARAMETER OBJECTS
The parameters found in the 3000h CAN Object address range are shown in
Table 3. All these parameters have Read/Write (RW) SDO access, except for
the sub-index 00h in a parameter array, which is Read Only (RO) as indicated.

Output Driver Mode 3000h 00h 6 Length of this array (RO).
01h – 06h 0 – 7 Binary value that sets each driver
0 – 7 to Input Only (0), Constant Current (1),
Note: a Constant Voltage (2), or Direct PWM (3)
setting of 4 mode.
is non-valid. Adding 4 to Modes 1, 2, or 3 will enable
the Driver Open Check (= 5, 6, 7).
Not applicable to Input Only mode.
Output Max Value 3001h 00h 6 Length of this array (RO).
01h – 06h
Voltage Mode Sets the maximum output that will be
0.0 – 80.0 V commanded when the PDO command
0 – 800 is 100%. Could be a current, a voltage,
Current Mode or a PWM % depending on the Mode
0.00 – 3.00 A setting.
0 – 300 The value and range will be
Direct Mode automatically changed when
0.0 – 100.0 % the Driver Mode is changed.
0 – 1000
Dither Period 3002h 00h 6 Length of this array (RO).
01h – 06h 4 – 200 ms Sets the time between dither pulses
4 – 200 for each output.
Resolution = 2 A Dither Period of 4 ms to 200 ms
provides a frequency range
of 250 Hz to 5 Hz.
Dither Amount 3003h 00h 6 Length of this array (RO).
01h – 06h 0 – 0.50 A Sets the amount (+/-) of dither
0 – 50 that will be added/subtracted
to the command. Only active when
the driver is in Constant Current mode.
Driver Proportional 3004h 00h 6 Length of this array (RO).
Gain 01h – 06h 1 – 100% Proportional gain factor of the
0 – 1000 PI Current Controller.
Driver Integral Gain 3005h 00h 6 Length of this array (RO).
01h – 06h 1 – 100% Integral gain factor of the
0 – 1000 PI Current Controller.
Nominal Battery 3010h 00h 12 – 80V Set to the nominal system/battery
120 – 800 voltage. This setting is used for detecting
both under and over voltage faults. See
Table 5 Troubleshoot Chart.
Analog Source 3020h 00h 0 – 3 Turns on/off the current sources
Enable 0 – 3 on Analog 1 or 2.
LSB is for Analog 1 and next
is for Analog 2.
Upper 6 bits are not used.
(Use bit = 1 to turn on source.)
