2-2-6 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.
3G3FV-PPGA2: A-phase (single) pulse input for open collector output, special-purpose V/f control
3G3FV-PPGB2: A/B-phase pulse input for open collector output, special-purpose vector control
3G3FV-PPGD2: A-phase (single) pulse input, line driver input, special-purpose V/f control
3G3FV-PPGX2: A/B/Z-phase pulse input, line driver input, special-purpose vector control
H Installing a PG Speed Control Card
1. Turn off the main-circuit power supply, and leave it off for at least one minute before removing the
front cover of the Inverter (or at least three minutes for Inverters of 30 kW or more). Check to be sure
that the CHARGE light is OFF.
2. Insert the spacer (which is provided) into the spacer hole in the Inverter's mounting base. For Invert-
ers of 3.7 kW or less, there are two adjacent holes. Insert the spacer into the 7CN hole. The spacer
cannot be easily removed if inserted into the wrong hole. Be very careful to insert the spacer into the
correct hole, and in the proper direction.
3. Referring to the enlarged illustration in the following diagram, align the PG Speed Control Card with
the catch position as shown by (1) and (2) and fit it precisely to the Option-A connector. Then pass
the spacer through the spacer hole at the Card. (Refer to illustration A.) Check to be sure that it is
precisely aligned with the 4CN position, and snap it into the proper position.
