6-2 MD60 AC Drive User Manual
6.1.1 Compliance with Machinery Safety Standard
EN 60204-1:1992
This section applies to you if you must comply with machinery
safety standard EN 60204-1:1992, part 9.2.5.4, Emergency Stop.
The MD60 drive coast-to-rest stop is a category 0 operational stop.
The ramp-to-rest stop is a category 1 operational stop. You can also
implement a category 2 stop with power maintained to the motor at
zero speed.
The required external hardwired emergency stop must be either a
category 0 or 1 stop, depending on your risk assessment of the
associated machinery. To fully comply with machinery safety
standard EN60204-1:1992, part 9.2.5.4, at least one of the two stop
methods must be a category 0 stop.
6.2 Motor Start/Stop Precautions
Important points to remember about I/O wiring:
• Always use copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control and signal wires should be separated from power wires
by at least 0.3 meters (1 foot).
!
ATTENTION: A contactor or other device that
routinely disconnects and reapplies the AC line to the
drive to start and stop the motor can cause drive
hardware damage. The drive is designed to use
control input signals that will start and stop the motor.
If used, the input device must not exceed one
operation per minute or drive damage can occur.
Failure to observe this precaution can result in
damage to, or destruction of, equipment.
ATTENTION: The drive start/stop control circuitry
includes solid-state components. If hazards due to
accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an
additional hardwired stop circuit may be required to
remove the AC line to the drive. When the AC line is
removed, there will be a loss of any inherent
regenerative braking effect that might be present -
the motor will coast to a stop. An auxiliary braking
method may be required.
