Personal Safety
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged completely before servicing. Remove power
and wait five minutes before you open the enclosure door. Measure the DC
bus voltage at the -DC and +DC TESTPOINT sockets on the front of the power
module (see Remove Power from the Drive System on page
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: 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.
ATTENTION: Hazard of personal injury or equipment damage due to
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.
Product Safety
ATTENTION: An incorrectly applied or installed drive can result in
component damage or a reduction in product life. Wiring or application
errors such as under sizing the motor, incorrect or inadequate AC supply, a
corrosive environment, or excessive surrounding air temperatures may result
in malfunction of the system.
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts
and assemblies. Static control precautions are required when installing,
testing, servicing or repairing this assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with static
control procedures, reference any applicable ESD protection handbook.
ATTENTION: Configuring an analog input for 0...20 mA operation and
driving it from a voltage source could cause component damage. Verify
proper configuration prior to applying input signals.
