Personal Safety

Risk of injury or death exists.

To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before servicing.

Measure the DC bus voltage at the power terminal block by measuring between the +DC and –DC terminals. Also, measure between the +DC terminal and the chassis, and between the –DC terminal and the chassis. The voltage must be zero for all three measurements.

Measure the DC bus voltage by measuring between the DC+ and DC– testpoint sockets on the bottom of the chassis. Also measure between the DC+ testpoint and PE ground bus bar (GND), and the DC– testpoint and the PE ground bus bar (GND).

Measure the DC bus voltage by measuring between the +DC and – DC testpoint sockets on the front of the power module. Also measure between the +DC testpoint and chassis GND, and the –DC testpoint and chassis GND.

Risk of injury or equipment damage exists.

Hazard of personal injury or equipment damage exists when using bipolar input sources. Noise and drift in sensitive input circuits can cause unpredictable changes in motor speed and direction. Use speed command parameters to help reduce input source sensitivity.

Risk of injury or equipment damage exists.

DPI™ or SCANport™ host products must not be directly connected together via 1202 cables. Unpredictable behavior can result if two or more devices are connected in this manner.

Risk of injury or death exists.

The drive start/stop/enable control circuitry includes solid state components. If hazards due to accidental contact with moving machinery or unintentional flow of liquid, gas or solids exists, an additional hardwired stop circuit may be required to remove the AC line to the drive. An auxiliary braking method may be required.

Risk of injury or equipment damage exists.

Unexpected machine operation exists if the drive is configured to automatically issue a Start or Run command. Do not use these functions without considering applicable local, national and international codes, standards, regulations or industry guidelines.

Risk of injury or death exists.

Potentially fatal voltages can result from improper usage of an oscilloscope and other test equipment. The oscilloscope chassis can be at a potentially fatal voltage if not properly grounded. If an oscilloscope is used to measure high-voltage waveforms, use only a dual channel oscilloscope in the differential mode with X 100 probes. It is recommended that the oscilloscope is used in the A minus B Quasi-differential mode and the oscilloscope chassis is grounded to an earth ground.

Risk of injury or death exists.

A possible hazard of personal injury due to prolonged exposure to high sound levels. Follow applicable local, national, and international codes, standards, regulations, or industry guidelines for hearing protection when exposed to potentially damaging noise hazards.
