Proper Wiring Methods -
Shielded cable is required for all signal wires connected to
the MicroSpeed 196, except for the AC input power. The shields should be tied on one
end only. Tie shields to the earth ground or common terminals provided on the
MicroSpeed 196.
Important: Never use shielded cable with unused conductors.
Unused conductors act as antennas and will corrupt your signals. Attempting to send
one signal down two wires, or grounding extra conductors will not prevent this from
happening.
Power Connection
-
Power to the MicroSpeed 196 is 115Vac (standard) or 230Vac
(optional), and is switch selectable. Power input to the MicroSpeed 196 should be as
clean as possible, so that the control circuitry is not exposed to spikes or other noise.
Noise immunity is built into the unit; however, care should still be taken. Terminal
locations for power are as follows:
TB2-22 = Line (L1)
TB2-23 = Neutral (L2)
TB2-24 = Chassis Ground

Connection to Drive -
The connection to the drive must be a shielded, twisted-pair
cable. The
Isolated Command Output
is connected to the input terminal on the
drive that is normally connected to the wiper of the speed potentiometer. The isolated
common terminal on the MicroSpeed 196 is connected to reference common on the
drive. Terminal locations are as follows:
TB2-2 = Isolated Command Output
TB2-3 = Isolated Common
EXTERNAL START/STOP SWlTCHES:
Run
- The
Run
input functions as a motor start, causing the MicroSpeed 196 to
ramp the motor speed to the selected set point. Typically, a
N.O. Momentary
switch is wired from
TB1-21 (Run
input) to common.
Stop
-
The
Stop
input functions as a motor stop, causing the MicroSpeed 196 to ramp
the motor speed down to zero. This also must be activated to clear a no feedback shut-
down error. Typically, a N.C.
Momentary
switch is wired from
TB1-22
(Stop
input)
to common.
IMPORTANT: If an external Stop switch is NOT used, jumper TB1-22 to TB1-23
(factory installed).
Single Contact Run/Stop
-
To control the Run/Stop function with a single contact,
jumper
Run
to
Stop
(
TB1-21
to
TB1-22
)
and switch to common (Open =
Stop,
Closed =
Run
).
When Run/Stop is used in this way, the front panel keypad
RUN
and
STOP
keys are disabled, and the
E-Stop
must be a N.C.
Maintained
contact.
E-STOP
-
The Emergency Stop input functions as an immediate stop. This function is
provided only on the terminal strip. The E-Stop should be used in emergency
situations only, because it overrides all other functions. Typically, a N.C.
Momentary
switch
is wired from terminal
TB1-24 (E-Stop)
to common.
IMPORTANT:
If
an external
E-Stop
switch is not used, jumper
TB1-24
to
TB1-23
(factory installed).
Jog -
The
Jog
input accelerates the motor to the programmed speed and stops the
motor when the contact is opened. (See “Section VII,
Programming-Jog Mode”
for
details.) Typically, an N.O. Momentary
switch is wired from TB1-19 (Jog) to common.
