Especially meant for blackouts. Spindle can keep on coasting foran hour in worst case.• New parameter 30.29 added which enables emergency ramp stop when drivefaults:- 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 emergencyramp stop deceleration time (par. 22.08).• Hardware critical faults (“ OVERCURRENT ”, “ DC OVERVOLT ” and “SHORTCIRC”) will still make a coast stop in order to protect the drive. When hardwarecritical faults occur among several other faults, the drive will make a coast stop.• “SAFE TORQUE OFF”, “STO1 LOST” and “STO2 LOST” faults will behave thesame way as hardware critical faults since it is not possible to drive the motoranyway.Related parameters are listed in the table below: SettingsParameter Additional information2208 EMERG DEC TIME Time within which the drive is stopped if anemergency stop is activated.3029 FAULT RAMP STOP Enables emergency ramp stop when drive faults
