Parker AC30 series User Manual

6-27 Safe Torque Off
AC30V series Variable Speed Drive
STO Function Checking
Two levels of checking are required: a comprehensive check and a regular check.
The user / machine builder must determine the frequency of these checks based on their knowledge, use of the machine, appropriate standards and
any legal requirements.
DANGER
ALL TESTS MUST PASS. IF ANY TEST FAILS, IT MUST BE INVESTIGATED AND RECTIFIED BEFORE ATTEMPTING TO PUT
THE EQUIPMENT INTO SERVICE.
FURTHER OPERATION OF THE AC30V WITHOUT RESOLVING THIS FAILURE IS ENTIRELY AT THE USER’S OWN RISK.
FAILURE TO DO SO COULD RESULT IN INJURY, DEATH OR DAMAGE. PARKER WILL NOT ACCEPT ANY LIABILITY FOR
FAILURE TO DO THIS OR FOR ANY CONSEQUENTIAL LOSS OR DAMAGE.
SEE SAFETY CATEGORY DEFINITIONS AND LIMITATIONS, REFER TO EN ISO 13849-1:2008.
When STO becomes active during any test, power to the motor must be seen by the user to be quenched instantaneously. Note: the drive should
respond in less than 10 milliseconds.
All STO checks should be performed after the AC30V has been commissioned for speed control.
