Digital Outputs (Includes Pulse Output) - ECM appsCAN Module Instruction Manual

Digital Outputs (includes Pulse Output)

Digital Outputs (PWM1, PWM2, PMW3, PWM4)
Notes:
1. Digital outputs are programmable in 8 or 16-bit PWM resolution mode. In 8-bit mode,
all four PWMs can be programmed. In 16-bit PWM resolution mode, only PWM2 and
PWM4 can be programmed.
2. Digital outputs can be programmed (in "Configure PWM Outputs" of Configuration
Tool) for:
i. 8-bit or 16-bit mode. In 8-bit mode worst case resolution: 0.4% Duty Cycle, 4 Hz.
In 16-bit mode worst case resolution: 0.008% Duty Cycle, 0.1 Hz.
ii. Pull-up (to 5V), or open-collector output
iii. Polarity Active Low (i.e. 100% duty cycle activates low-side driver and pulls output
to ground)
iv. Pulse Mode operation of the output. In this mode, a single pulse of programmable
width and delay (from clicking on "Start"). Once pulse mode is activated, the delay,
width, and triggering of the pulse are programmable in the "Configure & Start Pulse
Signal" task in the Configuration Tool.
v. The default duty cycle and frequency on power up.
3. PWMs are programmable for 0 to 100% Duty Cycle and 1.5 Hz to 1000 Hz
4. Programmable frequency FRQA is for PWM1 and PWM2. FRQB is for PWM3, PWM4.
5. Maximum voltage for low-side driving: 28 VDC
6. Maximum current sinking: 500 mA/channel
7. All digital outputs share a common ground
8. C/T# below means Connector/Terminal Number. The left (gray) terminal is "L", the
right (black) is "R". See Figure 1 below for connector and terminal numbering.
