Preface
General Precautions
Qualified Personnel
Personal Safety
ATTENTION: Only qualified personnel familiar with the PowerFlex 700S Drive
and associated machinery should plan or implement the installation, start-up
and subsequent maintenance of the system. Failure to comply may result in
personal injury and/or equipment damage.
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus
capacitors has discharged before performing any work on the drive. Measure the
DC bus voltage at the Power Terminal Block by measuring between the +DC and
–DC terminals, between the +DC terminal and the chassis, and between the -DC
terminal and the chassis. The voltage must be zero for all three measurements.
ATTENTION: 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.
ATTENTION: 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.
ATTENTION: Risk of injury or equipment damage exists. Parameters 365 [Fdbk
LsCnfg Pri]…394 [VoltFdbkLossCnfg] let you determine the action of the drive
in response to operating anomalies. Precautions should be taken to ensure that
the settings of the parameters do not create hazards of injury or equipment
damage.
ATTENTION: Risk of injury or equipment damage exists. Parameters 383 [SL
CommLoss Data]…392 [NetLoss DPI Cnfg] let you determine the action of the
drive if communications are disrupted. You can set the parameters so that the
drive continues to run. Precautions should be taken to ensure that the settings of
the parameters do not create hazards of injury or equipment damage.
