1 = 0x3370 0x00
2 = 0x3371 0x00
3 = 0x3372 0x00
4 = 0x3373 0x00
5 = 0x3374 0x00
6 = 0x3375 0x00
7 = 0x3376 0x00
8 = 0x3377 0x00
9 = 0x3378 0x00
10 = 0x3379 0x00
0.0 – 100.0 %
0 – 1000
The driver’s PWM percentage.
Note: Replace X with 1 – 10 for the specific
Driver_X_PWM
(See
).
100% equates to the driver being fully ON, meaning 100 percent of the Coil
Return voltage (B
+
) is applied to the load (e.g., contactor coil). See
50% equates to an applied voltage of 50%
0 % turns off the driver.

9 = 0x3338 0x00
10 = 0x3339 0x00
0.000 – 4.000 Amps
0 – 4000

11 = 0x337A 0x00
12 = 0x337B 0x00
0.0 – 100.0 %
0 – 1000
The driver’s PWM percentage.
Note: Replace X with 11 or 12 for the specific
Driver_X_PWM
Driver 11 = the HB Driver 1 (pin 23)
Driver 12 = the HB Driver 2 (pin 35)
100% equates to the driver being fully ON, meaning 100 percent of the
voltage (B
+
) is applied to the load (e.g., contactor coil or a motor).
50% equates to an applied voltage of 50%
0 % turns off the driver.
