2 Product Overview

2 Product Overview

◆ About This Product

The PG-B3 Option allows the user to connect an incremental encoder with complementary
output (PG) for motor speed feedback to the drive and take advantage of the V/f with PG,
Closed Loop Vector, and Closed Loop Vector for PM motors control modes. The option
helps increase the control accuracy and higher performance.

This PG encoder signal allows the drive to compensate for subtle variations in the load,
while providing the drive with the necessary data to control the output frequency and
maintain an accurate constant speed.

The PG-B3 Option reads a maximum input frequency from the PG encoder of 50 kHz. Be
sure to select an PG encoder with an output of maximum 50 kHz when operating at
maximum speed.

◆ Applicable Models

The option can be used with the drive models in Tab le 1 .

6. Route the option wiring.

B

A

Depending on the drive model, some drives may require routing the wiring through
the side of the front cover to the outside. In these cases, cut out the perforated
openings on the left side of the drive front cover as shown in Figure 10-A and leave
no sharp edges to damage wiring.
Route the wiring inside the enclosure as shown in Figure 10-B for drives that do not
require routing through the front cover.
Refer to the Peripheral Devices & Options section of the drive Technical Manual for

Figure 10

more information.

5 Installation Procedure

A – Route wires through the openings

provided on the left side of the
front cover.

<1> The drive will not meet NEMA Type 1 requirements if wiring is exposed outside the enclosure.

With a two-pulse or three-pulse PG encoder, the leading pulse determines the
motor rotation direction. A PG encoder signal with leading A pulse is considered to

Figure 12

Figure 13

be rotating forward (counter-clockwise when viewing rotation from motor load side).

Figure 12 Displacement of A and B Pulses

After connecting the PG encoder outputs to the option, apply power to the drive and
manually rotate the motor and check the rotation direction by viewing monitor U1-05
on the digital operator.
Reverse motor rotation is indicated by a negative value for U1-05; forward motor
rotation is indicated by a positive value.
If monitor U1-05 indicates that the forward direction is opposite of what is intended,
reverse the two A pulse wires with the two B pulse wires on option terminal TB1 as
shown in Figure 13.

Figure 13 A Channel and B Channel Wire Switching

If switching the wires is inconvenient, set drive parameter F1-05/F1-32 to 1 to switch
the direction of how the option reads pulses from the PG encoder output.
Please note that when the drive is initialized using A1-03 =1110, 2220, 3330, the
value for F1-05/F1-32 will reset to factory default and the parameter will need to be
adjusted again to switch the direction.

◆ Drive-Side Error Codes

Ta bl e 8 lists the various fault codes related to the option and pulse generator. Refer to the

drive Technical Manual for further details on fault codes.

Check the following items first when an error code occurs on the drive:

• Are the cables connected properly and securely?

• Is the option properly installed to the drive?

• Did a momentary power loss occur?

Table 8 Fault Displays, Causes, and Possible Solutions

Digital Operator Display Fault Name

dEv

Cause Possible Solution

The load is too heavy. Reduce the load.

The acceleration and
deceleration times are set too
short.

The load is locked up. Check the machine.

Parameters are set
inappropriately.

Motor brake is engaged. Ensure the motor brake releases properly.

Digital Operator Display Fault Name

dv1

Cause Possible Solution

The PG encoder is disconnected
or is not wired properly, or the
PG option or PG encoder are
damaged.

Digital Operator Display Fault Name

dv2

Cause Possible Solution

PG encoder cable noise
interference.

Speed Deviation (for Control Mode with PG)

The deviation between the speed reference and speed feedback is greater than the
setting in F1-10 for longer than the time set to F1-11.

Increase the acceleration and deceleration times (C1-01 through C1-08).

Check the settings of parameters F1-10 and F1-11.

Z Channel Pulse Fault Detection

The motor turned one full rotation while failing to detect the Z channel pulse.

• Rewire the PG encoder and make sure all wiring including shielded wiring is
properly connected.

• If the problem continues after cycling power, replace the PG option or the PG
encoder.

Z Channel Pulse Noise Fault Detection

The Z channel pulse is out of phase by more than 5 degrees for the number of
times specified in parameter F1-17.

Separate the PG encoder cable wiring from the source of the noise (e.g., drive
output wiring).

7 Troubleshooting

The PG encoder is disconnected
or is not wired properly, or the
PG option or PG encoder are
damaged.

Digital Operator Display Fault Name

dv3

Cause Possible Solution

The Z channel pulse offset is not
set properly to E5-11.

An external force on the load
side caused the motor to move.

Noise interference along the PG
encoder cable is affecting the A
channel or B channel.

The PG encoder is disconnected
or is not wired properly, or the
PG option or PG encoder are
damaged.

The PG encoder rotational
direction set to F1-05 is in the
opposite direction of the motor
wiring.

Digital Operator Display Fault Name

dv4

Cause Possible Solution

The Z channel pulse offset is not
set properly to E5-11.

Noise interference along the PG
encoder cable is affecting the A
or B pulse.

• Rewire the PG encoder and make sure all wiring including shielded wiring is
properly connected.

• If the problem continues after cycling power, replace the PG option or the PG
encoder.

Inversion Detection

• Torque reference and acceleration are in opposite directions.

• The speed reference and actual motor speed differ by over 30% for the number
of pulses set to parameter F1-18.

Set the value for Δθ to E5-11 as specified on the motor nameplate. Replacing the
PG encoder or changing the application so the motor rotates in reverse requires
readjustment of the Z channel pulse offset.

• Make sure the motor is rotating in the proper direction.

• Investigate problems on the load side causing motor rotation in the opposite
direction.

• Rewire the PG encoder and make sure all wiring including shielded wiring is
properly connected.

• If the problem continues after cycling power, replace the PG option or the PG
encoder.

Make sure motor wiring for each phase (U, V, W) is connected properly.

Inversion Prevention Detection

Pulses indicate that the motor is rotating in the opposite direction of the speed
reference. Set the number of pulses to trigger inverse detection to F1-19.
Note: To avoid nuisance faults, be sure to disable inverse detection in applications
where the motor may rotate in the opposite direction of the speed reference. Set
F1-19 to 0 to disable this feature.

• Set the value for Δθ to E5-11 as specified on the motor nameplate.

• If the problem continues after cycling power, replace the PG option or the PG
encoder.
Replacing the PG encoder or changing the application so the motor rotates in
reverse requires readjustment of the Z channel pulse offset.

• Make sure the motor is rotating in the proper direction.

• Investigate problems on the load-side that may be causing the motor to rotate in
the opposite direction.

that option.

Switch the power off and reconnect the option.

Switch the power off and reconnect the option.

Overspeed

The motor speed feedback exceeded the F1-08 setting.

• Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce
C5-02 (Speed Control Integral Time 1).

• Enable Feed Forward Control and perform Inertia Auto-Tuning in CLV.

• Set H6-02 to the value of the speed feedback signal frequency when the motor
runs at the maximum speed.

• Adjust the input signal using parameters H6-03 through H6-05.

Check and correct parameter F1-01.

Check the setting for the overspeed detection level and the overspeed detection
time (F1-08 and F1-09).

Control Method Selection Error

Correct the setting for the control method.

• Connect a PG option.

• Correct the value set to A1-02.

◆ Preventing Noise Interference

Take the following steps to prevent erroneous operation caused by noise interference:

• Use shielded wire for the PG encoder signal lines.

• Limit the length of all motor output power cables to less than 100 m. Limit the length of
open-collector output lines to less than 50 m.

• Separate the control wiring to the option, main circuit input power wiring, and motor
output power cables.

• Ground the shield on the PG encoder side and the drive side. If noise problems arise in the
PG encoder signal, verify that the shield is properly grounded and ground one end of the
signal line or remove the ground connection on both ends.
