2-10 Cs1W-Pmv02 Isolated-Type Analog Output Unit - Omron SYSMAC CS Series Operation Manual

CS1W-PMV02 Isolated-type Analog Output Unit
Outputs are Not Converted as Intended.
Probable cause
The zero/span adjustment or
high/low limit value is incorrect.
An output device's I/O specifica-
tions do not conform.
The rate-of-change limit is too
low, and the change is too slow.
Outputs are Unstable.
Probable cause
Output signals are being affected
by external noise.
Answer Input Data Does Not Change.
Probable cause
The gain for span adjustment is
set to 0.
An output device is malfunction-
ing, output wiring is faulty, or wir-
ing is disconnected.
Values are Not Converted as Intended.
Probable cause
The zero/span adjustment, high/
low limit, or rate-of-change value
is incorrect.
An output device's I/O specifica-
tions do not conform.
Converted Values are Unstable.
Probable cause
Output signals are being affected

Overview
120
Check and correct the settings.
Check the load impedance
Change the remote device.
Correct the rate-of-change limit setting.
Change the connection paths of the output signal lines. (Separate them from sources
of noise or use shielded cable.)
Set the gain for span adjustment to a value other than 0.
Check whether the output voltage or current has changed. Check for faulty or discon-
nected wiring. Check whether a disconnection has been detected in the I/O Area.
Check and correct the settings.
Check the load impedance
Change the remote device.
Change the connection paths of the output signal lines. (Separate them from sources
of noise or use shielded cable.)
Increase the number of values for calculating the moving average in mean value pro-
cessing.
Each cycle, the CS1W-PMV02 Isolated-type Analog Output Unit converts up
to four analog output set values from the CPU Unit to analog voltage signals
and outputs them.
