Resetting STO condition
If STO is activated while running the motor then this condition is latched
(similar to a trip, but not part of trip log list in Emotron AC drive). Blinking
“STO” will be shown as indication to the user as described above.
If STO is activated while in standby mode (motor stopped) then blinking
“STO” will be shown as indication to the user as described above. This
condition is NOT latched as it is triggered while motor is in stopped state.
To reset latched STO condition, do the following:
•
Check if the cause for activating the STO condition has been resolved
•
Enable safety input terminals (by pro24Vdc)
•
Give a STOP signal to the Emotron AC drive by falling edge on digital
input set to function STOP (Run/Stop Control signal in menu [21A]
should be set to edge to comply with the Machine Directive).
•
In case [215] Run/Stp control is set to keyboard you also have to press the
RESET button on the control panel.
•
If [215] Run/Stp control is set to Com you have to cancel existing Run-
command via communication by setting the corresponding bit of either
Run, RunR or RunL low.
To restart the motor after STO condition:
•
Give a new RUN command to the Emotron AC drive by rising edge on dig-
ital input set to function RUN (Run/Stop Control signal in menu [21A]
should be set to edge to comply with the Machine Directive)
•
If [215] is set to Keyboard: After pressing reset button to clear STO condi-
tion the AC drive can be resetarted by pressing the RUN button again
•
If [215] is set to Com: Give a new RUN command to the Emotron AC
drive by setting bit RUN high as well as either RunL or RunR depending on
selected shaft direction
NOTE: The user must secure that external measures according to EN ISO
13849-1 are provided to ensure that the Emotron AC drive only can be
restarted after a confirmation (following reset procedure).
