NOTE: The resistance of the earth ground conductor must be ≤ 10 Ω.
Grounding Robot-Mounted Equipment
The following two parts of an eCobra robot are not grounded to protective earth: the Joint 3
quill and the tool flange. If hazardous voltages are present at any user-supplied robot-mounted
equipment or tooling, you must install a ground connection from that equipment or tooling to
the ground point on the robot base. Hazardous voltages can be considered anything in excess
of 30 VAC (42.4 VAC peak) or 60VDC.
Also, for the grounding point on the tool flange, see Figure 8-6.
WARNING: ELECTROCUTIONRISK
Failing to ground robot-mounted equipment or tooling that uses hazardous
voltages could lead to injury or death of a person touching the end-effector
when an electrical fault condition exists.
4.8 Configuring a PLC
A PLC is user-supplied. This section describes how to configure your PLC for automatic star-
tup when the system boots.
1.
Start the ACE software.
2.
Open the Controller object.
3.
In the Configure tab, select Configure Controller, then click Finish.
