Product Overview

About This Product
The PG-X3 Option allows the user to connect an incremental line driver encoder (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 performance.
This PG 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-X3 Option reads a maximum input frequency from the PG of 300 kHz. Be sure to select a PG with an output of maximum 300 kHz when operating at maximum speed.
Note: This option cannot be used with an open collector encoder. Use option PG-B3 with open collector encoders.

Installing the Option

Remove the front covers of the drive before installing the option. Refer to the drive manual for directions on removing the front covers. Cover removal varies depending on drive size.

1. Shut off power to the drive, wait the appropriate amount of time specified on the drive for voltage to dissipate, then remove the digital operator (E) and front covers (D, F).
   
   Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Before wiring terminals, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. After shutting off the power, wait at least the amount of time specified on the drive before touching any components.
   
2. Insert the option (B) into the CN5-B (K) or CN5-C (L) connectors located on the drive and fasten it into place using one of the included screws (C).
   Use the CN5-C connector (L) when connecting only one option to the drive; use both CN5-B and CN5-C when connecting two options.
   Connect one of the ground wires (H) to the ground terminal (I) using one of the remaining screws (C). Connect the other end of the ground wire (H) to the remaining ground terminal and installation hole on the option using the last remaining provided screw (C).
   
   Note:
   1. The option package includes two ground wires. Use the longer wire when plugging the option into connector CN5-C on the drive side. Use the shorter wire when plugging the option into connector CN5-B. Refer to Option Package Contents for more information.
   2. There are two screw holes on the drive for use as ground terminals. When connecting three options, two ground wires will need to share the same drive ground terminal.
3. Route the option wiring.
   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 5 (A) and leave no sharp edges to damage wiring.
   Route the wiring inside the enclosure as shown in Figure 5 (B) for drives that do not require routing through the front cover.
   For more information, refer to the Peripheral Devices & Options section of Yaskawa AC Drive Technical Manual in your application.
   
   Figure 5 Wire Routing Examples
   1. Route wires through the openings provided on the left side of the front cover.<1>
   2. Use the open space provided inside the drive to route option wiring.
      1. The drive will not meet NEMA Type 1 requirements if wiring is exposed outside the enclosure.
4. Prepare wire ends as shown in Figure 6. Refer to Wire Gauges and Tightening Torques to confirm that the proper tightening torque is applied to each terminal. Take particular precaution to ensure that each wire is properly connected and wire insulation is not accidentally pinched into electrical terminals.
   
   Fire Hazard. Tighten terminal screws to the specified tightening torque. Loose electrical connections could result in death or serious injury by fire due to overheating. Tightening screws beyond the specified tightening torque may cause erroneous operation, damage the terminal block, or cause a fire.
   NOTICE: Heat shrink tubing or electrical tape may be required to ensure that cable shielding does not contact other wiring. Insufficient insulation may cause a short circuit that can damage the option or drive.
   
5. Wire the motor PG encoder to the terminal block on the option. Refer to Figure 7 for wiring instructions.
   Refer to Option Terminal Functions for a detailed description of the option board terminal functions.
   Parameter Settings and Connections for Different Encoder Types
   • Connecting a Single-Channel Encoder
     When using a single-channel encoder in V/f with PG control mode, connect the pulse output from the PG to the option and set drive parameter F1-21 to 0.
   • Connecting a Two-Channel Encoder
     When using a two-channel encoder, connect the A and B pulse outputs on the PG to the option and set F1-21 to 1.
     When using a two-channel encoder in Closed Loop Vector control mode, connect pulse outputs A and B from the encoder to the corresponding terminals on the option.
   • Connecting a Two-Channel Encoder with Z Marker Pulse
     When using a two-channel encoder with Z marker pulse, connect the A channel, B channel, and Z pulse outputs to the corresponding terminals on the option.

   Control Method	V/f with PG		Closed Loop Vector
   No. of Encoders	1 CN5-C	2 CN5-B	1 CN5-C	2 CN5-B
   Single Channel (A)	F1-21 = 0	F1-37 = 0	N/A	N/A
   Two Channel (AB Quadrature)	F1-21 = 1	F1-37 = 1	No setting required	No setting required
   Two Channel with Marker (ABZ)	F1-21 = 1	F1-37 = 1	No setting required	No setting required

1. Ground the shield on the PG side and the drive side. If noise problems arise in the PG signal, remove the shield ground from one end of the signal line or remove the shield ground connection on both ends.

6. Set the voltage for the PG power supply using jumper CN3 located on the option. Position the jumper as shown in Table 2 to select the voltage level.
   NOTICE: The positioning of jumper CN3 selects the PG power supply voltage (5.5 V or 12 V). Select the voltage level for the PG connected to the option and motor. If the wrong voltage is selected, the PG may not operate properly or may become damaged as a result.
   Table 2 Setting PG Power Supply Voltage (IP) with Jumper CN3

   Voltage Level	5.5 V ± 5% (default)	12.0 V ± 5%
   Jumper CN3

7. Replace and secure the front covers of the drive (D, F) and replace the digital operator (E).
   
   Note: Take proper precautions when wiring the option so that the front covers will easily fit back onto the drive. Make sure cables are not pinched between the front covers and the drive when replacing the covers.
8. Set drive parameters for proper motor rotation.
   With a two-channel or three-channel encoder, the leading pulse determines the motor rotation direction. A PG signal with leading A pulse is considered to be rotating forward (counter-clockwise when viewing rotation from motor load side).
   
   After connecting the PG 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 channel wires with the two B channel wires on option terminal TB1 as shown in Figure 10.
   
   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 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.

Wire Gauges, Tightening Torque, and Crimp Terminals

Wire gauge and torque specifications are listed in Table 3. Yaskawa recommends using crimp terminals with the specifications listed in Table 4 to facilitate wiring and ensure proper connection.
Table 3 Wire Gauges and Tightening Torques

Crimp Terminals

Yaskawa recommends using CRIMPFOX 6 by Phoenix Contact or equivalent to crimp the terminal ends.
Note: Properly trim wire ends so loose wire ends do not extend from the crimp terminals.

Troubleshooting

Preventing Noise Interference

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

• Use shielded wire for the PG signal lines.
• Limit the length of all motor output power cables to less than 100 m.
• Separate the control wiring to the option, main circuit input power wiring, and motor output power cables.
• Ground the shield on the PG side and the drive side. If noise problems arise in the PG signal, verify that the shield is properly grounded and ground one end of the signal line or remove the ground connection on both ends.

Interface Circuit

Drive-Side Error Codes

Table 7 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:

• Make sure the PG cable is properly connected.
• Check the cables between the PG and the option.
• Make sure the option is properly installed to the drive.

Table 7 Fault Displays, Causes, and Possible Solutions

Digital Operator Display		Fault Name
	dEv	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.
Cause		Possible Solution
The load is too heavy.		Reduce the load.
The acceleration and deceleration times are set too short.		Increase the acceleration and deceleration times (C1-01 through C1-08).
The load is locked up.		Check the machine.
Parameters are set inappropriately.		Check the settings of parameters F1-10 and F1-11.
Motor brake is engaged.		Ensure the motor brake releases properly.
Digital Operator Display		Fault Name
	dv1	Z Channel Pulse Fault Detection
		The motor turned one full rotation while failing to detect the Z channel pulse.
Cause		Possible Solution
The PG encoder is disconnected or is not wired properly, or the PG option or PG are damaged.		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.
Digital Operator Display		Fault Name
	dv2	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.
Cause		Possible Solution
PG cable noise interference.		Separate the PG cable wiring from the source of the noise (e.g., drive output wiring).
The PG encoder is disconnected or is not wired properly, or the PG option or PG are damaged.		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.
Digital Operator Display		Fault Name
	dv3	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.
Cause		Possible Solution
The Z channel pulse offset is not set properly to E5-11.		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.
An external force on the load side caused the motor to move.		Make sure the motor is rotating in the proper direction. Investigate problems on the load side causing motor rotation in the opposite direction.
Noise interference along the PG cable affecting the A channel or B channel.		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.
The PG encoder is disconnected or is not wired properly, or the PG option or PG are damaged.
The PG encoder rotational direction set to F1-05 is in the opposite direction of the motor wiring.		Make sure motor wiring for each phase (U, V, W) is connected properly.
Digital Operator Display		Fault Name
	dv4	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.
Cause		Possible Solution
The Z channel pulse offset is not set properly to E5-11.		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.
Noise interference along the PG is cable affecting the A or B pulse.		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.
PG encoder is disconnected or is not wired properly, or the PG option or PG are damaged.		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.

Cause		Possible Solution
Option at drive port CN5-C was changed during run.		Switch the power off and reconnect the option.
Digital Operator Display		Fault Name
	oPE06	Control Method Selection Error
		Correct the setting for the control method.
Cause		Possible Solution
Control mode requires installing a PG option, but no PG encoder is installed (A1-02 = 1, 3, or 7).		Connect a PG option. Correct the value set to A1-02.
Digital Operator Display		Fault Name
	oS	Overspeed
		The motor speed feedback exceeded the F1-08 setting.
Cause		Possible Solution
Overshoot is occurring.		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.
Incorrect speed feedback scaling when terminal RP is used as speed feedback input in V/f control.		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.
Incorrect PG pulse number set.		Check and correct parameter F1-01.
Inappropriate parameter settings.		Check the setting for the overspeed detection level and the overspeed detection time (F1-08 and F1-09).
