1-30 Installation/Wiring
speed reference is issued by the PLC through a communications module
installed in the drive. Since the internal communications is designated as
Port 5, [Speed Ref A Sel] is set to “DPI Port 5” with the drive running from
the Auto source. Since the Manual speed reference is issued by an analog
input (“Analog In 1 or 2”), [TB Man Ref Sel] is set to the same input. To
switch between Auto and Manual, [Digital In4 Sel] is set to “Auto/
Manual.”
Attain Manual Control
• Close the digital input.
With the input closed, the speed command comes from the
potentiometer.
Release to Auto Control
• Open the digital input.
With the input open, the speed command returns to the PLC.
Auto/Manual Notes
1. Manual control is exclusive. If a HIM or Terminal Block takes manual
control, no other device can take manual control until the controlling
device releases manual control.
2. If a HIM has manual control and power is removed from the drive, the
drive will return to Auto mode when power is reapplied.
CE Compliance Low Voltage Compliance
The LPM15 drive is compliant with the essential requirements of the Low
Voltage Directive 73/23/EEC when installed according to this user manual
including the Notes and Requirements of this section. Compliance with the
Low Voltage Directive has been demonstrated using the harmonized
European standard EN 50178.
EMC Compliance
The LPM15 drive as supplied by Rockwell Automation does not satisfy the
essential requirements of the EMC Directive 89/336/EEC. Compliance with
the EMC Directive is the responsibility of the machine builder incorporating
the LPM15 into an overall machine. The LPM15 produces conducted and
radiated electromagnetic emissions which can interfere with other
equipment, and the machine builder must provide appropriate mitigation to
insure that the LPM15 does not disturb other equipment.
