Additional Safety Precautions
Motor Case Grounding
Insure that the motor’s case is connected to PE ground. The fourth wire in the motor cable
connecting J2-1 or TB1-1 to the motor case accomplishes this.
CAUTION
If the motor is not properly grounded, dangerous voltages can be
present on the motor case due to capacitive coupling between the
motor windings and case.
Requirements for Safe Operation of the Drive
It is the machine builder’s responsibility to insure that the complete machine complies with the
Machine Directive (EN60204).
The following requirements relate directly to the servo controller:
1. Emergency Stop
CAUTION
If personal injury can result from motor motion, the user must provide an
external hardwired emergency stop circuit outside the drive. This circuit
must simultaneously remove power from the drive’s motor power terminal
J2-2, J2-3, and J2-4 or TB1-2, TB1-3, and TB1-4 and disable the drive (by
open circuiting the connection to J4 pin 2).
NOTE
The motor will coast under this condition with no braking torque.
CAUTION
If braking torque is required to quickly stop the motor, a dynamic brake can
be added that loads the motor’s windings resistively. The motor should not
be loaded until the servo drive is disabled.
The holding brake, optional on
Danaher Motion motors, is not intended to stop a spinning motor. It is
designed to prevent a stopped motor from rotating due to an applied torque.
2. Avoid Unexpected Motion
CAUTION
Always remove power from J1 or TB1, J1 and wait 5 minutes before working
on the machine or working anywhere where injury can occur due to machine
motion.
3. Avoid Electrical Shock
CAUTION
Never power the servo drive with the cover removed or with anything
attached to circuitry inside the cover.
If the drive must be removed from the cabinet, wait at least five minutes
after turning off power before removing any cables from the drive or
removing the drive from the mounting panel.
Never connect or disconnect any wiring to the drive while power is
applied. Always power down and wait five minutes before connecting or
disconnecting any wires to the terminals.
4. Avoid Burns
CAUTION
The temperature of the drive’s heat sink and housing as well as an external
regen resistor may exceed 60° C. Therefore, there is a danger of severe
burns if these regions are touched.
5. Prevent Damage to the Drive
Follow these guidelines to prevent damage to the servo drive during operation:
Never plug or unplug connectors with power applied.
Never connect or disconnect any wires to terminals with power applied.
If the drive indicates a fault condition, find the cause of the fault and fix it prior to resetting
the fault or power-cycling the drive.
