Using PG Speed Control Board
There are four types of PG Speed Control Board that can be used in V/f control with PG.
• PG-A2: A-phase (single) pulse input, compatible with open collector or complimentary outputs.
•
•
•
PG-B2: A/B-phase pulse input, compatible with complimentary outputs.
PG-D2: A-phase (single) pulse input, compatible with line drivers.
PG-X2: A/B/Z-phase pulse input, compatible with line drivers.
There are two types of PG Speed Control Boards that can be used for flux vector control.
• PG-B2: A/B phase pulse inputs, complementary outputs
• PG-X2: A/B/Z phase pulse inputs, line driver outputs
For the connection diagram, refer to page 2-36 to 2-38.
Setting Number of PG Pulses
Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or Bphase pulses per 1 motor rotation in F1-01.
Matching PG Rotation Direction and Motor Rotation Direction
Constant F1-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating forwards, set whether it is A-phase driven or B-phase driven. Make this setting when using PG-B2 or PG-X2.

Yaskawa standard PG used is A-phase driven (CCW) when motor rotation is forward.
Fig 6.78 PG Rotation Direction Setting
Generally, PG is A-phase driven when rotation is clockwise (CW) see from the input axis. Also, motor rotation is counter-clockwise (CCW) seen from the output side when Forward Commands are output. Consequently, when motor rotation is forward, PG is normally A-phase driven when a load is applied, and B-phase driven when a load is not applied.
Options
Setting Number of Gear Teeth Between PG and Motor
Set the number of PG gear teeth in F1-12 and F1-13. If there are gears between the motor and PG, you can operate the motor by setting the number of gear teeth.
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated using the following formula.
No. of motor rotations (min
− 1
.) = No. of input pulses from PC × 60 / F1-01 × F1-13 (No. of gear teeth on load side) / F1-12 (No. of gear teeth on motor side)
Matching Motor Speed During Acceleration and Deceleration to Frequency Reference
You can select whether to enable or disable integral operation during acceleration and deceleration when using
V/f with PG control.
To match the motor speed as closely as possible to the frequency reference even during acceleration and deceleration, set F1-07 to 1.
If F1-01 is set to 1, overshoot or undershoot may occur easily immediately after acceleration and deceleration. To minimize the possibility of overshoot or undershoot occurring, set F1-01 to 0.
IMPORTANT
Setting PG Pulse Monitor Output Dividing Ratio
This function is enabled only when using PG speed control board PG-B2. Set the dividing ratio for the PG pulse monitor output. The set value is expressed as n for the higher place digit, and m for the lower place 2 digits. The dividing ratio is calculated as follows:
Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32
F1-06 = n
m
The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the dividing ratio is
1/2 (set value 2), half of the number of pulses from the PG are monitor outputs.
Detecting PG Open Circuit
Select the stopping method when PG cable disconnected is detected and the PG open circuit (PGO) detection time.
When the Inverter is operating with the frequency reference set to 1% minimum (except when operating on direct current), if the speed feedback from PG is greater than the time setting in F1-14, PGO is detected.
Detecting Motor Overspeed
An error is detected when the number of motor rotations exceeds the regulated limit. An overspeed (OS) is detected when a frequency that exceeds the set value in F1-08 continues for longer than the time set in F1-09.
After detecting an overspeed (OS), the Inverter stops according to the setting in F1-03.
Detecting Speed Difference between the Motor and Speed Reference
An error is detected when the speed deviation (i.e., the difference between the designated speed and the actual motor speed) is too great. Speed deviation (DEV) is detected after a speed agreement is detected and when the speed reference and actual workpiece speed are within the setting of L4-02, if a speed deviation great than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the
Inverter stops according to the setting in F1-04.

Using an Analog Reference Board (SPEC: E or Later Only)
AI-14B provides 3 channels of bi-polar inputs with 13-bit A/D conversion accuracy (and a + sign bit). The function of each channel is determined by the setting of F2-01.
AI-14U provides 2 channels of bi-polar inputs with 14-bit A/D conversion accuracy. Channel 1 is a voltage input and channel 2 is a current input. The sum of channels 1 and 2 is a frequency input. F2-01 does not need to be set for the AI-14U.

2 (Option/Inverter selection).
Using a Digital Reference Board (SPEC: E or Later Only)
When using a DI-08 or DI-16H2 Digital Reference Board, set b1-01 (Reference selection) to 3 (Option
Board).
The DI-16H2 can be used to set a frequency using a 16-bit digital reference. The DI-08 can be used to set a frequency using a 8-bit digital reference.

Application Precautions
•

The maximum frequency (100% speed) reference will be used when the binary input is set (setting: 6 or 7) and all bits are 1.
Setting F3-01 to 6 is valid only when the D1-16H2 is used. Using this setting, a frequency from 0.00 to
399.8 Hz can be set in BCD. The sign bit is used as a data bit, so only positive (plus) data can be set. Also, the digit starts from 0, so the minimum setting is 0.02 Hz.
Selecting the Input Terminal Function for a DI-08 Digital Reference Board
The frequency reference from a DI-08 Board is determined by the setting of F3-01, as shown in the following table.
