3.7 Installing and Wiring PG Speed Control Cards

PG Speed Control Cards are used for executing speed control using a pulse generator (PG). There are four types

of PG speed control, as shown below. Select the type that fits the application and control method.

PG-A2

A-phase (single) pulse input for open collector output or complementary outputs, for V/f control

PG-B2

A/B-phase pulse input for open collector output or complementary outputs, for vector control

PG-D2

A-phase (single) pulse input for line driver input, for V/f control

PG-X2

A/B/Z-phase pulse input for line driver input, for vector control

3.7.1 Installing a PG Speed Control Card

Use the following procedure to install a PG Speed Control Card.

1. Turn OFF the main-circuit power supply of the Inverter Panel.
2. Leave it OFF for at least five minutes before opening the front door of the Inverter Panel. Check to be

sure that the CHARGE lamp is OFF.

3. After aligning to the Option-A connector on the control PCB located on the back of the front panel of

the Inverter Panel, pass the spacer through the spacer hole at the Card. (Refer to A in the illustration.)

Check to be sure that it is precisely aligned with the 4CN position, and snap it into the proper position.

Be sure to press it in firmly until you hear it snap into place.
