•
Read and understand this bulletin in its entirety before installing
or operating the ALTIVAR 58 drive controllers. Installation,
adjustment, repair, and maintenance of these drive controllers
must be performed by qualified personnel.
•
Disconnect all power (including external control power that may
be present) before servicing the drive controller. Wait three
minutes for the DC bus capacitors to discharge. Follow the DC
Bus Voltage Measurement procedure on page 3 to verify that the
DC voltage is less than 45 V. The drive controller LEDs are not
accurate indicators of the absence of DC bus voltage.
•
DO NOT short across DC bus capacitors or touch unshielded
components or terminal strip screw connections with voltage
present.
•
Install and close all doors and covers before applying power or
starting and stopping the drive controller.
•
User is responsible for conforming to applicable code
requirements with respect to grounding all equipment. For drive
controller grounding points, refer to the terminal connection
drawing in the installation guide delivered with the drive controller
being serviced.
•
Many parts in this drive controller, including printed wiring boards,
operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
Before servicing drive controller:
•
Disconnect all power.
•
Place a “DO NOT TURN ON” label on the drive controller
disconnect.
•
Lock the disconnect in the open position.
Electrical shock will result in death or serious injury.

3.
4.
Perform the Bus Voltage Measurement Procedure on page 3 to be
certain that hazardous voltage is not present in the controller.
With the hinged cover open, fold the flexible shield installed over the
control board to the left. Note that the flexible shield is not shown in
Figure 1.
Mount the option card by aligning it with the locating pins on either
side of the connector on the control board. Gently press the card onto
the connector pins.
Visually verify that the card is properly seated, then tighten the three
mounting screws.

BUS VOLTAGE MEASUREMENT PROCEDURE
DANGER
HAZARDOUS VOLTAGE
• Read and understand the Bus Voltage Measurement Procedure
before performing this procedure. Measurement of bus capacitor
voltage must be performed by qualified personnel.
• DO NOT short across DC bus capacitors or touch unshielded
components or terminal strip screw connections with voltage
present.
• Many parts in this drive controller, including printed wiring boards,
operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
Electrical shock will result in death or serious injury.
The DC bus voltage level is determined by monitoring the + and –
measurement points. The location of the measurement points varies by
drive controller model; Table 1 below and Figure 2 on page 4 show the
measurement locations for each drive controller model. The model
number of the drive controller is listed on the controller’s nameplate.

7.
Verify that the DC voltage has discharged below 45 V before
servicing the drive controller.
If the bus capacitors do not discharge below 45 V, contact your local
Square D representative. Do not operate the drive controller.
8.
Replace all covers after servicing the drive controller.
WIRING
Good wiring practice requires the separation of control circuit wiring from
all power wiring. This separation reduces the possibility of coupling
electrical noise from power circuits or from the motor into control circuits.
When wiring the analog I/O extension card, follow the wiring practices
required by national and local electrical codes as well as those listed in
the installation guide shipped with your ALTIVAR 58 drive controller.
Terminate the multiple conductor cable shield wires at the drive controller
terminal designated for this purpose. Refer to the installation guide for
your type of ALTIVAR 58 drive controller for the location of this terminal.
For information concerning electromagnetic compatibility, refer to your
installation guide.
I/O Characteristics

•
•
•
•
•
•
Two 24 Vdc logic inputs
One ±10 Vdc bipolar differential analog input
One 24 Vdc open collector logic output
One 0–20 mA analog output (output range adjustable)

To calculate the total value of R1 + R2, use the maximum current of the
tachometer, which equals 10 mA.
maximum tach. voltage 120 Vdc
Total resistance = ------------------------------------------------------------- = ---------------------- = 12 kΩ
maximum tach. current
0.01A
To calculate each resistance, use the average voltage at the inputs,
7 Vdc.
Total resistance × 7 Vdc 12 kΩ × 7 Vdc
Value of R1 = ---------------------------------------------------------------- = --------------------------------------- = 700 Ω
Maximum voltage
120 Vdc
The closest standard value is 680 Ω .
Value of R2 = Total resistance – R1 = 12 kΩ – 0.680 kΩ = 11.32 kΩ
The closest standard value is 11 kΩ .
Therefore, the exact voltage at AI3 is:
0.68kΩ
120 Vdc × R1 / (R1 + R2) = 120 Vdc × ----------------------- = 6.99 Vdc
11.68kΩ
Use 2 W power resistors. To scale speed feedback precisely, adjust the
tachometer scaling factor (dtS) at the time of installation.
