Digital Output Configuration
Two output signals are available which may be configured for ON/OFF, PWM, or SERVO outputs through the Output
Configuration registers (0x0124 and 0x0126). The remaining outputs are assigned as phantom devices which are
non-configurable. The highlighted entries show typical default configurations.

7.5.1 Rate
The Rate determines the repetition rate, or frequency, of the Digital Output. For On/Off outputs the rate
field is ignored.
7.5.1.1 PWM Rate
The SP-013 supports the following PWM frequencies:
PWM Rate
Name
Description
0
100 Hz
PWM signal has constant 100 Hertz frequency (10 msec repetition
rate) with 0 – 100 % duty cycle
1
10 Hz
PWM signal has constant 10 Hertz frequency (100 msec repetition
rate) with 0 – 100 % duty cycle
2
1 Hz
PWM signal has constant 1 Hertz frequency (1-second repetition
rate) with 0 – 100 % duty cycle
3
0.1 Hz
PWM signal has constant 0.1 Hertz frequency (10-second
repetition rate) with 0 – 100 % duty cycle
