Input Wiring Board Signal Descriptions
The tables below and on the following pages provide descriptions of
the various control signals shown in Figure 5.1.
Wire: Description: Connects to terminal(s):
Mandatory
or Optional:
A VREF +
A VREF - The drive will accept up to a +/-10V DC velocity command
signal to achieve maximum motor speed. Voltages lower than
+/-10V DC can be used by reprogramming (Anlg Vel Scal). You
must terminate the shield at one end only. The differential
impedance of the velocity command input is 80k ohms (40k
ohms for single ended inputs). TB1 and TB2 terminals 1,
2, 3, 8, 9, and 10 Optional
A TQREF +
A TQREF - The drive will accept up to a +/-10V DC torque command signal
to achieve maximum torque command. Shield must be
terminated at one end only. The differential impedance of the
command input is 80k ohms (40k ohms for single ended
inputs).
3V DC = +/- 100% rated motor current. TB1 and TB2 terminals 4,
5, 6, 11, 12, and 13 Optional
ENABLE Normal run commands to the drive are performed through the
Enable input and any additional user-supplied run control
circuitry. With 24V control power (W1, W2), three-phase input
power (U, V, W), Contactor Enable (TB2-16, 17) and Drive OK
(TB2-18, 19) applied, 24V DC user-supplied to this input
enables the axis. When this input is de-energized, a
regenerative braking action occurs on the motor. TB1 and TB2 terminals 7
and 14 and TB2 terminal
15 Mandatory
FAULT RESET Removing the Axis Enable signal and applying 24V DC
between this terminal and signal common (TB1-19) resets the
fault.
Important: Do not perform a Reset until you have determined
the cause of the fault and corrected it. TB1 terminal 15 Mandatory
ANALOG OUT 1/
ANALOG COM Motor current analog is available on TB1-16. It is scaled for
3.3V DC for 100% continuous rated motor current (10V DC =
300% motor rated current). Minimum load impedance between
TB1-16 and 18 is 10K ohm. This can be linked to other
parameters. TB1 terminal 16 and 18 Optional
ANALOG OUT 2/
ANALOG COM Motor velocity analog is available on TB1-17. It is scaled for
2.0V DC per 1000 rpm. Minimum load impedance between
TB1-17 and 18 is 10K ohm. This can be linked to other
parameters. TB1 terminal 17 and 18 Optional
COM
TB1-19 must be connected to the ground bar with 3.3 mm
2
(12
AWG) wire.
TB1 terminal 19 Mandatory
CHASSIS Chassis ground reference terminal. TB1 terminal 20 Optional
CONTACTOR EN A set of contacts for energizing the user’s three-phase line
contactor coil TB2 terminals 16 and 17 Mandatory
DROK When you apply 24V AC/DC control power to the system and
no system faults are detected, the Drive OK relay contact
closes. It can also be programmed for fault only, ignoring the
bus voltage. The contact remains closed until a drive fault
occurs, DC bus voltage is lost, or you remove 360/480V input
power from the system module depending on how you set the
Drive OK mode parameter. If a drive fault is detected or the DC
bus voltage is lost, the relay contact opens. You can wire the
Drive OK contacts into the stop string to open the main power
contactor if a fault occurs. The contact rating is 115V AC or 24V
DC, 1A. DROK is located at CR2. TB2 terminals 18 and 19 Optional
