CAUTION
To avoid damage to the connector and drive, NEVER plug or unplug J1 with
power applied.
J1-1 or Chassis
Screw PE
Protective Earth
This chassis ground point
must be connected to
Protective Earth ground
. The connection at the
Protective Earth ground end
must be hard wired
(do not use a pluggable connection). A ground
fault detector (RCD) cannot be depended on for
safety.
J1-2 or TB1-5
REGEN
Connection for an optional regeneration power
resistor to absorb regenerated energy from the
motor. Models S20260 and S20360 typically use
36
Ω
. S20660, S21260 typically use 12.5
Ω
, and
S22460 typically uses 8
Ω
. Other values within
the min to max resistance specification range can
be used. Use a Wire wound resistor with 1500
V
RMS
isolation between terminals and case. Many
applications do not require a regen resistor. If
over-voltage faults occur during motor
deceleration, then the more kinetic energy is being
returned to the bus capacitors than they can
handle. Connect the proper Ohmage 50 to 1000
watt power resistor from this terminal, to terminal
J1-4 (+BUS) in order to eliminate the over-voltage
faults. The power rating of the regen resistor
depends on the amount of regenerated energy
that needs to be dissipated.
WARNING
The regen input is not short circuit protected. The regen resistance MUST
be within specified ranges to prevent damage to the drive. For example,
S20260, S20360 drives must be between 25 to 50
Ω
.
NOTE
For safety, either mount the external resistor on a grounded panel or wire it
to a grounded connection. The terminals of the resistor MUST NOT be
grounded.
WARNING
Wait 5 minutes after power is removed for the bus cap voltage to decay to a
safe level before touching the regen resistor or wiring. Monitor the voltage
on the bus caps with a voltmeter from +BUS (J1-4) to -BUS (J1-3).
J1-3 or TB1-6
-BUS
The -BUS terminal is usually left open during
normal operation. In special multi-axis
applications, drive buses can be wired in parallel
to allow returned energy from one motor to power
another and limit high regen powers.
J1-4 or TB1-7
+BUS
The +BUS terminal is used with the J1-2, REGEN,
terminal to add a regen resistor to the drive to
absorb regenerated energy.
J1-5, J1-6
