Motor Case Grounding
Ensure that the motor’s case is connected to PE ground. The fourth wire in the motor cable
connecting J2,1 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 amplifier:
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 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.
Avoid Unexpected Motion
CAUTION
Always remove power from J1 and wait 5 minutes before working on the machine or
working anywhere where injury can occur due to machine motion.
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.
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.
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.
