Description Category 1 definition IEC/EN 60204-1 defines category 1 emergency stop as a controlled stop with the power to machine actuators available to achieve the stop and then removal of power when the stop is achieved. Implementation of category 1 stop in ACS800 in brief After the emergency stop command has been given, the drive first decelerates the motor to a standstill according to a preset ramp time.
Components of the emergency stop function The following pieces of equipment are included: Line contactor or air circuit breaker. See Alternative drive configurations on page 54. Operating switch Position ACS800-07 ACS800-17/37 The supply rectifier stops and the line Cooling fans are disabled. (Other auxiliary contactor or air circuit breaker opens.

Earth fault monitoring in IT (ungrounded) systems (+Q954) What this chapter contains This chapter describes earth fault monitoring option +Q954 in IT (ungrounded) systems. The chapter deals with applicability, wiring, operation and use. Example circuit diagrams are included. The chapter also describes the internal earth fault protection of the drive in short.
AINT Current board Σ I transducers Note concerning parallel-connected inverter modules There is some current deviation between parallel-connected inverter modules due to slight differences in the components. Motor cabling of parallel-connected inverter modules produces cable stray capacitances in a larger scale than in single inverters. When the IGBTs are switched, high-frequency common mode current flows through these stray capacitances to earth.
Internal earth fault protection of the ACS800-17/37 The drive is equipped with a similar earth fault protection against earth faults in the motor cable or motor as in the ACS800-07. In addition, the drive is equipped with an earth fault protection against earth faults in the input cable and line-side converter based on input current sum measurement.
Applicable standards The following standards concern earth fault monitoring in IT systems: • IEC/EN 60204-1:1997 “Safety of machinery – Electrical equipment of machines – Part 1: General requirements”. • IEC 60364-4-41:2001 “Electrical installations of buildings – Protection for satefy – Protection against electrical shock”.

The monitoring device is connected between the ungrounded system and the drive grounding conductor (PE). The IRDH275 monitors the insulation resistance of the IT system. L1 L2 L3 Transformer Supply unit Inverter units DC busbar BENDER insulation monitoring device Fault current A pulsating AC measuring voltage is superimposed on the system (measuring principle Adaptive Measuring Pulse, developed by BENDER).
Operation principle of the IRDH275 The internal structure of the IRDH275 is presented below with a simplified circuit diagram in case of an earth fault in V-phase. Earth fault Bender IRDH275 Earth fault in V-phase When there is no earth fault, the measuring voltage U (direct voltage) does not cause direct current to flow through earth.
Technical data Bender insulation monitoring device IRDH275-435 Nominal voltage: 0…793 VAC, 0…650 VDC Resistance response values for Alarm 1 and Alarm 2: 1 kohm …10 Mohm Supply voltage: 88…230 VAC Wiring Typically, the user connects a relay output(s) on the insulation monitoring device to an overriding system.
