Fault reaction for EM STOP
Emergency ramp stop in case of non critical faults and 500ms delayed fault for under
voltage controller. Especially meant for blackouts. Spindle can keep on coasting for
an hour in worst case.
• New parameter 30.29 added which enables emergency ramp stop when drive
faults:
- 30.29 = 0 Fault reaction same as in standard FW.
- 30.29 = 1 Drive makes ramp stop during fault (except HW critical faults).
• Drive makes an emergency ramp stop when fault occurs using the emergency
ramp stop deceleration time (par. 22.08).
• Hardware critical faults (“ OVERCURRENT ”, “ DC OVERVOLT ” and “SHORT
CIRC”) will still make a coast stop in order to protect the drive. When hardware
critical faults occur among several other faults, the drive will make a coast stop.
• “SAFE TORQUE OFF”, “STO1 LOST” and “STO2 LOST” faults will behave the
same way as hardware critical faults since it is not possible to drive the motor
anyway.
