5SGY35L4510 ABB Drive control thyristor module

Description

The robot has two Emergency Stop push buttons.
– One is located on the operators panel.
– The other is located on the teach pendant.
Both Emergency Stop buttons have normally closed
contacts. When the Emergency Stop button is pressed,
the button will remain pressed in and will open the
contacts.
If the Emergency Stop circuitry is opened:
a) The robot will stop immediately.
b) The motors will have power disconnected from
them.
c) An error (20002 – Emergency Stop) will be generated
on the teach pendant.
d) The “ES” LED (on the system board) will go off
indicating that the run chain has been interrupted.
e) When the LED goes OFF, KM1 and KM2 relays will
open, removing power from the drives.
To reset the button, either twist the button or pull on
button until it returns to its OUT position. Press the ‘OK’
button on the Teach Pendant to clear the error.
You are also required to press the Motors OFF
button to reset the emergency stop condition. Both
Emergency Stop buttons also have dual contacts, one
for each run chain.
The robot also supplies two 24 VDC circuits on XS3/
XT3 (customer connections) for the customer to wire
into the emergency stop circuitry. There are circuits
provided for both run chains.
It is important to use both run chain circuits to ensure
proper error identification by the computer. If only one
run chain circuit is used, run chain errors will appear
instead of emergency stop errors.
This chapter is in three sections. One for Run Chain 1,
one for Run Chain 2, and the third for the circuits used
to reset an Emergency Stop.
