Digital Output Control (Terminal B3) - Emerson 2202 Advanced User's Manual

Introduction
x.00 description format
NOTE
The thermistor going short circuit will not damage the drive.
NOTE
When Pr 8.35 is set to th, the mode button will need to be pressed four times to return the drive display to status mode. This ensures that this setting
is saved.
When terminal B7 is set as motor thermistor input, Pr 1.41 is no longer assigned to terminal B7 therefore analog reference 2 is no longer selected.
Analog reference 1 should be used.
There is no parameter to display the motor temperature.
Connect the motor thermistor between 0V and terminal B7.

input
In modes 2 and 3, terminal B7 will function as a frequency input as described in menu 3.
The frequency input destination parameter, Pr 8.25 will be scaled by the maximum reference frequency, Pr 3.43. For example, (from default), setting
Pr 8.25 =1.21 and Pr 3.43=2kHz, with a frequency input of 1kHz on terminal B7, Pr 1.21 will be 25Hz.
NOTE
The amplitude of the frequency input must be above 15V peak to peak. The threshold voltage is 10V.

This parameter offers a simple control of Pr 8.21 to change the functionality of the digital output.
Its function is used to set the value of Pr 8.21 to one of the parameters listed below.

3 hEAL
4 Act
5 ALAr

A user wishing to change the digital output to something other than the one's listed above or using the terminal as an input, must first program this
parameter to 8. Pr 8.21 should then be programmed to the desired unprotected parameter.
