Caution: Avoid locating control immediately above or beside heat generating equipment, or
directly below water or steam pipes.
Caution: Avoid locating control in the vicinity of corrosive substances or vapors, metal
particles and dust.
Caution: For UL installations, do not connect any resolver cable shields to the motor frame. At
a minimum, resolver signal integrity will be compromised and damage to the control may result.
For CE installations, refer to CE guidelines stated in Sections 3 and A1 of this manual.
Caution: Do not connect AC power to the control terminals U, V and W. Connecting AC power
to these terminals may result in damage to the control.
Caution: Harmonic Drive recommends not using „Grounded Leg Delta“ transformer power
leads that may create ground loops and degrade system performance. Instead, we recommend using
a four wire Wye.
Caution: Logic signals are interruptible signals; these signals are removed when power is
removed from the drive.
Caution: Controls are intended to be connected to a permanent main power source, not a
portable power source. Suitable fusing and circuit protection devices are required.
Caution: The safe integration of the drive into a machine system is the responsibility of the
machine designer. Be sure to comply with the local safety requirements at the place where the
machine is to be used. In Europe this is the Machinery Directive, the ElectroMagnetic Compatibility
Directive and the Low Voltage Directive. In the United States this is the National Electrical code and
local codes.
Caution: Controls must be installed inside an electrical cabinet that provides environmental
control and protection. Installation information for the drive is provided in this manual. Motors and
controlling devices that connect to the drive should have specifications compatible to the drive.
Caution: Violent jamming (stopping) of the motor shaft during operation may damage the
motor and control.
Caution: Do not tin (solder) exposed wires. Solder contracts over time and may cause loose
connections.
Caution: Electrical components can be damaged by static electricity. Use ESD (electro–static
discharge) procedures when handling this control.
Caution: Ensure that resolver or encoder wires are properly connected. Incorrect installation
may result in improper rotation or incorrect commutation.
Caution: The holes in the top and bottom of the enclosure are for cable clamps. Be sure to use
an M4 bolt 12mm in length. Longer bolts may short circuit the electrical components inside the
control.
