5.9.2. Parameter reset using the optional push button
Depending on the encoder type the encoder may have a screw cap located where connectors and LEDs are
located as well. After removing the screw cap the push button is visible.
An encoder with a button is shown in chapter 3.2.3.
In the first 60 seconds after switching on the encoder pushing the button resets the following settings:
All IP settings (IP address, subnet mask, standard gateway) are set to the value 0.0.0.0.
The station n
ame („device name“) is set an empty string.
For firmware version 1.2.x this has to be considered:
Resetting of IP settings and station name is only done if the encoder has
no
Ethernet connection.
Since firmware version 1.3.0 this has to be considered:
Resetting of IP settings and station name is done independent of the fact that the encoder has an
Ethernet connection or not.
Additionally to resetting of IP settings and station name the following actions are done:
o
Reset of following encoder parameters to the following values:
Parameter
Value
Scaling functionality
on
Code sequence
cw
Measuring units per revolution
default value
Total measuring range
default value
“Speed measuring unit”
rpm
“Speed update period”
16 ms
“Speed filter depth”
1
“Gear factor: activation”
off
“Gear factor: numerator”
default value
“Gear factor: denominator”
1
Requested preset value (see PNU 65000)
0
o
Reset of the internal preset offset to 0
o
Re
start (“software reset”) of the encoder
Note:
Prior to using the push button it is strictly recommended to execute a potential equalization between operator
and encoder (touching the encoder housing) in order to eliminate the danger of damaging the encoder by
electrostatic discharge (ESD).
For firmware version 1.2.x this has to be considered:
-
In order to perform a reset the push button must be pressed within 60 seconds after power-on of the
encoder for a duration of at least three seconds and longest five seconds.
-
After the reset it is necessary to switch the encoder off and on again.
Since firmware version 1.3.0 this has to be considered:
-
In order to perform a reset the push button must be pressed within 60 seconds after power-on of the
encoder (LEDs blinking red). The button has to be released when the LEDs change from red blinking
to green blinking.
-
After the reset it is not necessary to switch the encoder off and on again. The encoder performs a
restart autonomously.
Note:
The reset using the push button is not fully congruent with the „Factory Setup“ according to PROFINET
specification via the DCP protocol (see chapter 5.9.1 „Factory Setup using the Engineering Tool“).
