Signal Description
Simulated tachometer output signal derived from resolver with a range
from -10V to +10V with a full scale of 3000 or 6000 RPM selected
through SW1/1.
The command signal is a DC signal in the range -10V to +10V
proportional to the requested current value. When ±10V is applied the
drive generates peak current. A positive signal with respect to common
(pin 3) will produce a counterclockwise shaft rotation. A negative signal
with respect to common will produce a clockwise shaft rotation. Shaft
rotation direction is viewed from the front of the motor.
Signal common. This terminal is not internally connected to the Earth
ground on the power connector.
Drive enable input. 1 (10 to 30VDC) = drive enable. O or open circuit =
drive disable (10 K W input impedance). The drive should be disabled
for a few seconds after applying power and should be disabled before
removing power. This way, the drive will power up in a stable fashion.
Voltage reference output +10V (max load 10mA)
Voltage reference output -10V (max load 10mA)
Non inverting input for speed command signal. Positive signal will
produce CW motion as seen when facing the motor shaft.
Inverting input for speed command signal. Positive signal will produce
CCW motion as seen when facing the motor shaft.
See pin 10 description.
Terminal pins 9 and 10 are internally connected through a contact when
the green LED lights and the drive is running. If a fault is active, the
contact is open. The contact drive capability is 5A 30V DC. If an LX
drive is connected to the back up supply, when the main supply falls,
the "Drive OK" green LED goes off for about 2 seconds then lights
again. The DRIVE OK contacts follow the green LED operation. In
back up status the drive is disabled, the green LED is ON and the
DRIVE OK contacts are closed.
Signal common. This terminal is not internally connected to the Earth
ground on the power connector.
This pin is normally at zero volts being pulled down to logic common
through an open collector transistor in the amplifier. When the red High
IRMS led lights during current limiting, this terminal becomes an open
circuit. The maximum voltage rating is 47V. The current drive
capability at logic 0 (grounded) is 100 mA.
Signal common. This terminal is not internally connected to the Earth
ground on the power connector.
The terminal pin is normally connected to the motor thermal sensor.
Link with terminal 13 if not used (default).
