INFORMATION
External filter shall be used for non-EMI version drives to
keep CE EMC compliance. Refer to installation manual for
detailed information of external filter. If an external filter
type other than recommended in the manual is used, the
CE EMC compliance shall be reconfirmed first. Please
contact the factory or your local Eaton sales representative
if necessary.

Requirement for installation, commission,
maintenance
A three-pin terminal block in control board (STO in
Figure 32
)
is used for customer to connect emergency stop switch.
When finished the installation, the STO function shall be
verified. Refer to
Figure 33
for the detailed wiring method.
The emergency stop switch for STO shall be closed state
normally.
The STO function shall be verified according to following
steps:
•
Apply main power to DM1.
•
Run the motor and wait until the motor operating stably.
•
Open the switch of STO1 or STO2, both “STO Fault” and
“Safety Torque Off” shall be triggered and the motor shut
down. Fault codes are FC 23 and FC 66.
•
Closed STO1 and STO2 switches.
•
Restart motor and wait until the motor operating stably.
•
Open the switches of STO1 and STO2 at the same time,
only “Safety Torque Off” shall be triggered and the motor
shut down. Fault code is FC 66.
•
Closed STO1 and STO2 switches. Test finished.
otes:

•
STO fault indicates two different fault types. One is the
drive internal circuit fault and the other is the case that
two STO input signals are not consistent within 200 ms.
•
If the customer needs more detailed information or the
test result is mismatched, please contact the factory or
your local Eaton sales representative.
