Safety 19
Safe start-up and operation
 General safety
These warnings are intended for all who plan the operation of the drive or operate the
drive.
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• After changing or maintaining the fan, make sure that the bottom cover is correctly
attached before connecting voltage to the drive. Keep the bottom cover attached
during operation.
• Before adjusting the drive and putting it into service, make sure that the motor and
all driven equipment are suitable for operation throughout the speed range
provided by the drive. The drive can be adjusted to operate the motor at speeds
above and below the speed provided by connecting the motor directly to the
power line.
• Do not activate any automatic fault reset functions of the drive control program if
d
angerous situations can occur. When activated, these functions will reset the
drive and resume operation after a fault.
• Do not control the motor with an AC contactor or disconnecting device
(disconnecting means); instead, use external commands via fieldbus or the I/O of
the drive. The maximum allowed number of charging cycles of the DC capacitors
(i.e. power-ups by applying power) is one per two minutes.
• Make sure that any safety circuits (for e
xample, emergency stop and Safe torque
off) are validated in start-up. See chapter Start-up for reference of the validation
instructions.
• The drive is not field repairable. Never attempt to repair a malfunctioning drive;
contact your local ABB representative or Authorized Service Center for
replacement.
• When operating a rotary motor with no load coupled to its shaft, remove the shaft
key to prevent it flying out when the shaft rotates.
• Operating the MicroFlex e190 in torque mode with no load attached to the motor
ca
n cause the motor to accelerate rapidly to excessive speed.
• Improper operation or programming of the drive may cause violent motion of the
motor and driven equipment. Be certain that unexpected motor movement will not
cause injury to personnel or damage to equipment. Peak torque of several times
the rated motor torque can occur during control failure.
• Violent jamming (stopping) of the motor during operation may damage the motor
and drive.
• The drive can be programmed to start up and begin to turn the motor (auto-
enable) immediately after an input voltage break or a fault reset. If an external
