Clicking the
PWM
tab will display the
PWM Configuration
page allowing you enable and configure the
PWM parameters for the PETL/tET/tPET device, including the PWM Alarm and duty cycle, etc., each of
which will be described in more detail below.
4.4.1 PWM Configuration
The following table provides an overview of the parameters contained in the PWM Configuration
section:
Item
Description
Default Value
Enable PWM
This parameter is used to enable the PWM output function.
0
Enable PWM Alarm
This parameter is used to enable the PWM output alarm function.
0
Duty Cycle
This parameter is used to set the duty cycle for the DO channels.
Two values are required for each DO channel.
The first value is the high pulse width, while the second is the low
pulse width. The duty cycle is in 1 ms units, and the resolution is
approximately 5 ms. (5 to 65535 ms). A value of 0 will disable the
duty cycle functions for that channel.
Refer to “Appendix: FAQ D” for more detailed information.
1000 (ms)
Update Settings
Click this button to save the revised settings to the PETL/tET/tPET device.
Because of the characteristics of the relay functions, it is recommended that the PWM on
t(P)ET-P(D)2POR2/ t(P)ET-P2R2/ t(P)ET-PD2R1/PETL-7060 series modules(i.e., modules with relay
functions) is not used for extended periods of time.
