NOTE:

2. Voltage or current input for the master frequency reference can be selected by constant n042. Voltage reference input is preset at the factory (FV).

3. Control circuit Terminal FS of + 15V has a maximum output current capacity of 20 mA.

4. Multi-function analog output should be used for monitoring meters (e.g., output frequency meter) and should not be used for feedback control system.

3.2 Wiring the Main Circuit

Make sure to ground the ground terminal ( ). (Ground resistance 200V class: 100Ω or less, 400V class: 10× or less.) Failure to observe this can result in an electrical shock or a fire.

Never connect the AC main circuit power supply to output Terminals T1, T2, and T3 (U, V and W). The Inverter will be damaged and invalidate the warranty.

3.2.1 Wiring Precautions for Main Circuit Input

§ Installation of Molded Case Circuit Breaker (MCCB)

Make sure to connect Molded Case Circuit Breakers (MCCB) or fuses between AC main circuit power supply and FP5/GP5 input Terminals L1, L2 and L3 (R, S, and T) to protect wiring.

indicates twisted-pair shielded wires.indicates shielded wires and

WARNING

CAUTION

§ Installation of Ground Fault Interrupter

When connecting a ground fault interrupter to input Terminals L1, L2 and L3 (R, S, and T), select one that is not affected by high frequency.

Examples: NV series by Mitsubishi Electric Co., Ltd. (manufactured in or after 1988), EG, SG series by Fuji Electric Co., Ltd. (manufactured in or after 1984).

§ Installation of Magnetic Contactor

Inverters can be used without a Magnetic Contactor (MC) installed at the power supply side. When the main circuit power supply is shut OFF in the sequence, a MC can be used instead of a MCCB. However, when a MC is switched OFF at the primary side, regenerative braking does not function and the motor coasts to a stop.

• The load can be operated/stopped by opening/closing the MC at the primary side. However, frequent switching

may cause the Inverter to malfunction.

• When using a Braking Resistor Unit, use a sequencer to break power supply side on overload relay trip contact.

If the Inverter malfunctions, the Braking Resistor Unit may be damaged.

§ Terminal Block Connection Sequence

Input power supply phases can be connected to any terminal regardless of the order of L1, L2 and L3 (R, S, and T) on the terminal block.

§ Installation of AC Reactor

When connecting an Inverter (200V/400V 15kW or less) to a large capacity power supply transformer (600k VA or more), or when switching a phase advancing capacitor, excessive peak current flows in the input power supply

circuit, which may damage the converter section. In such cases, install a DC Reactor (optional) between Inverter ¾ 1 and ¾ 2 terminals or an AC Reactor (optional) on the input side. Installation of a reactor is effective for

improvement of power factor on the power supply side.

§ Installation of Surge Suppressor

§ Prohibition of Installation of Phase Advancing Capacitor

3.2.2 Wiring Precautions for Main Circuit Output

§ Connection of Terminal Block and Load

§ Strict Prohibition of Connection of Input Power Supply to Output Terminals

§ Strict Prohibition of Short Circuiting or Grounding of Output Circuit

For inductive loads (magnetic contactors, magnetic relays, magnetic valves, solenoids, magnetic brakes, etc.) connected near the Inverter, use a surge suppressor simultaneously.

If a Phase Advancing Capacitor or Surge Suppressor is connected in order to improve the power factor, it may become overheated and damaged by Inverter high harmonic components. Also, the Inverter may malfunction because of overcurrent.

Connect output Terminals T1, T2, and T3 (U, V, and W) to motor lead wires T1, T2, and T3 (U, V, and W). Verify that the motor rotates in the forward direction (CCW: counterclockwise when viewed from the motor load side) with the forward RUN command. If the motor rotation is incorrect, exchange any two of output Terminals T1, T2, and T3 (U, V, and W).

Never connect the input power supply to output Terminals T1, T2, and T3 (U, V, and W).

Never touch the output circuit directly or put the output line in contact with the Inverter case. Otherwise, it may cause an electrical shock or grounding. In addition, never short-circuit the output line.

§ Prohibition of Connection of Phase Advancing Capacitor or LC/RC Noise Filter

Never connect a Phase Advancing Capacitor or LC/RC noise filter to the output circuit.

§ Avoidance of Installation of Magnetic Starter

Do not connect a Magnetic Starter or MC to the output circuit. If the load is connected while the Inverter is running, the Inverter overcurrent protective circuit operates because of inrush current.

§ Installation of Thermal Overload Relay

An electronic overload protective function is incorporated into the Inverter. However, connect a Thermal Overload Relay when driving several motors with one Inverter or when using a multi-pole motor. When using a Thermal Overload Relay, set Inverter constant n033 to 0 (motor overload protection selection: no protection). Additionally, for Thermal Overload Relay at 50Hz, set the same rated current value as that described on the motor nameplate, or at 60Hz 1.1 times larger than the rated current value described on the motor nameplate.

§ Wiring Distance between Inverter and Motor

If the total wiring distance between Inverter and motor is excessively long and the Inverter carrier frequency (main transistor switching frequency) is high, harmonic leakage current from the cable will adversely affect the Inverter and peripheral devices.

If the wiring distance between Inverter and motor is long, reduce the Inverter carrier frequency as described below. Carrier frequency can be set by constant n050.

3.2.3 Grounding

• Ground resistance

• 200 V class: 100 Ω or less, 400 V class: 10 Ω or less

• Never ground the Inverter in common with welding machines, motors, or other large-current electrical equipment.

Run all the ground wires in a conduit separate from wires for large-current electrical equipment.

Firmware – S2011 and S3012 Revision: 1 (9/98) 12 © Saftronics, Inc.

3.3.2 Wiring the Control Circuit Terminals

Insert the wire into the lower part of the terminal block and connect it tightly with a screwdriver. Wire sheath strip length must be 7 mm (approximately ¼ inch).

3.3.3 Precautions on Control Circuit Wiring

• Separate control circuit wires from main circuit wires and other power cables to prevent erroneous operation caused

by noise interference.

• Use twisted shielded or twisted-pair shielded wire for the control circuit line and connect the shielded sheath to the

Inverter Terminal G. See Figure 12.

3.4 Wiring Inspection

After completing installation and wiring, check for the following items. Never use control circuit megger check.

o Wiring is proper. o Wire clippings or screws are not left in the unit. o Screws are securely tightened. o Bare wire in the terminal does not contact other terminals.

efesotomasyon.com - Control Techniques,emerson,saftronics -ac drive-servo motor

WARNING

Only turn ON the input power supply after replacing the front cover. Do not remove the cover while current is flowing. Failure to observe this can result in an electrical shock.

When the retry function (n057) is selected, do not approach the Inverter or the load, since it may restart suddenly after being stopped. (Construct machine system, so as to assure safety for personnel, even if the Inverter should restart.) Failure to observe this can result in personal injury.

Since the stop button can be disabled by a function setting, install a separate emergency stop switch. Failure to observe this can result in personal injury.

CAUTION

Never touch the heatsink or discharging resistor since the temperature is very high. Failure to observe this can result in harmful burns to the body.

Since it is easy to change operation speed from low to high speed, verify the safe working range of the motor and machine before operation. Failure to observe this can result in personal injury and machine damage.

• Install a holding brake separately if necessary. Failure to observe this caution can result in personal injury.

• Do not change signals during operation. The machine or the Inverter may be damaged.

All the constants of the Inverter have been preset at the factory. Do not change the settings unnecessarily. The Inverter may be damaged. For supply voltage, follow Paragraph 4.3 of Chapter 4.

4.1 Operation Mode Selection

efesotomasyon.com - Control Techniques,emerson,saftronics -ac drive-servo motor

The FP5/GP5 has two operation modes, LOCAL and REMOTE, as described in Table 9. These two modes can be selected by the Digital Operator LOCAL/REMOTE key only while the operation is stopped. The selected Operation mode can be verified by observing the Digital Operator SEQ and REF LED’s as shown below. The Operation mode is set to REMOTE (run by control circuit Terminals FV and FI frequency reference and RUN command from a control circuit terminal) prior to shipment. Multifunction contact inputs from control circuit Terminals S3 to S6 are enabled in both Operation modes LOCAL/REMOTE.

• LOCAL : Both frequency reference and RUN command are set by the Digital Operator. SEQ and REF LED’s go OFF.

• REMOTE : Master frequency reference and RUN command can be selected as described in Table 9.

4.2 Test Run Checkpoints

To assure safety, prior to initial operation, disconnect the machine coupling so that the motor is isolated from the machine. If initial operation must be performed while the motor is still coupled to the machine, use great care to avoid potentially hazardous conditions. Check the following items before a test run.

o Wiring and terminal connections are correct. o No short-circuit caused by wire clippings. o Screw-type terminals are securely tightened. o Motor is securely mounted o All items are correctly earthed (grounded).

4.3 Setting the Line Voltage Using Jumper (For 400V Class 18.5kW and Above)

Set the line voltage jumper according to the main circuit power supply. (See Figure 13.) Insert the jumper at the appropriate location corresponding to the input line voltage. It has been preset at the factory to 440V.

efesotomasyon.com - Control Techniques,emerson,saftronics -ac drive-servo motor

Sets the Inverter to restart and reset fault detection after a fault occurs. The number of self-diagnosis and retry attempts can be set in n056 up to 10. The Inverter will automatically restart after the following faults occur:

• OC (overcurrent)

• OV (overvoltage)

• UV1 (undervoltage PUV) (when n051 = 1 is selected)

• GF (ground fault)

• rr (regenerative transistor fault)

The number of retry attempts are cleared to 0 in the following cases:

• If no other fault occurs within 10 minutes after retry.

• When the fault reset signal is ON after the fault is detected.

• Power supply is turned OFF.

6.3.13 Operating Coasting Motor without Trip

To operate coasting motor without trip, use the Speed Search command or DC Injection Braking at start.

§ Speed Search Command

Restarts a coasting motor without stopping it. This function enables smooth switching between motor commercial power supply operation and Inverter operation.

Set multi-function contact input selection (constants n035 to n039) to 15 (Search command from maximum output frequency) or 16 (Search command from set frequency).

Build a sequence so that FWD or REV RUN command is input at the same time or after the Search command. If the RUN command is input before the Search command, the Search command becomes disabled.

Following is a time chart at Search command input.

6.4 Selecting Stopping Method

6.4.1. Selecting Stopping Method (n004)

Selects the stopping method suitable for the application.

Setting Description

0 Deceleration to stop (Factory setting) 1 Coast to stop 2 Coast to stop with timer 1 3 Coast to stop with timer 2

§ Deceleration to Stop (n004 = 0)

Figure 36 Stopping Method

(Deceleration to Stop)

Upon removal of the FWD or REV RUN command, the motor decelerates at the deceleration rate determined by the time set to decel time 1 (n020), and DC Injection Braking is applied immediately before stop. If the decel time is short or the load inertia is large, an overvoltage (OV) fault may occur at deceleration. In this case, increase the decel time or install an optional Braking Resistor (can be equipped with GP5).

Braking torque : Without Braking Resistor : Approximately 20% torque of motor rating

With Braking Resistor : Approximately 150% torque of motor rating

§ Coast to Stop (n004 = 1)

Figure 37 Stopping Method

(Coast to Stop)

6.6 Adjusting Motor Torque

6.6.1. Torque Compensation Gain (n067)

Motor torque requirement changes according to load conditions. Full-range automatic torque boost adjusts voltage of V/f pattern according to the requirement. The FP5/GP5 automatically adjusts the voltage during constant-speed operation as well as during acceleration. The required torque is calculated by the Inverter.

Output voltage ∝ Torque compensation gain (n067) 5 Required torque

• Operation

Normally, no adjustment is necessary for torque compensation gain (n067 factory setting: 1.0). When the wiring distance between the Inverter and the motor is long, or when the motor generates vibration, change the torque compensation gain.

Increasing torque compensation gain increases motor torque, but an excessive increase may cause the following:

• Inverter malfunctions because of motor overexcitation.

• Motor overheat or excessive vibration.

Increase torque compensation gain gradually while verifying the motor current.

6.7 Motor Protection

efesotomasyon.com - Control Techniques,emerson,saftronics -ac drive-servo motor

6.7.1. Motor Overload Detection

The Inverter protects against motor overload with a built-in electronic Thermal Overload Relay.

§ Motor Rated Current (n032)

Set to the rated current value shown on the motor nameplate.

§ Motor Overload Protection Selection (n033)

Setting Electronic Thermal Characteristics

0 No protection 1 Standard motor (time constant 8 minutes) (Factory setting) 2 Standard motor (time constant 5 minutes) 3 Inverter motor (time constant 8 minutes) 4 Inverter motor (time constant 5 minutes)

The electronic Thermal Overload Relay function monitors motor temperature, based on Inverter output current and time, to protect the motor from overheating. When electronic Thermal Overload Relay is enabled, an OL1 error occurs, shutting OFF the Inverter output and preventing excessive overheating in the motor.

When operating with one Inverter connected to one motor, an external Thermal Overload Relay is not needed. When operating several motors with one Inverter, install a Thermal Overload Relay on each motor. In this case, set constant n033 to 0.

§ Standard Motor and Inverter Motor

Induction motors are classified as standard motors or Inverter motors, based on their cooling capabilities. Therefore, the motor overload function operates differently between these two motor types.

6.8 PID Control

To enable PID Control, set PID selection (n084) from 1 to 3.

Setting Description

0 PID disabled 1 PID enabled (Deviation I D-controlled.) 2 PID with feed forward (Feedback value is D-controlled.) 3 PID with feed forward (Feedback is reversed characteristics.)

Then select the PID Control intended value or detected value settings as follows.

6.8.1. Intended Value Setting

For setting the intended value, control circuit Terminal FV voltage signal (0 to 10 V) or multi-step speed constants n025 to n029 can be used.

Control circuit Terminal FV voltage signal: Set Operation mode selection (n002) to 2 or 3. Multi-step speed constants (n025 to n029): Set Operation mode selection (n002) to 0 or 1. (Combination of multi-step

speed reference and jog frequency reference.)

6.8.2. Detected Value Setting

For setting the detected value, control circuit Terminal FI current signal (4 to 20mA) or voltage signal (0 to 10 V) can be used.

Control circuit Terminal FI current signal: Set auxiliary analog input selection (n043) to 1. Control circuit Terminal FI voltage signal: Set auxiliary analog input selection (n043) to 0. (Cut jumper J1 on the control

PC board.) The following shows the block diagram of PID Control.

Figure 49 PID Control Block Diagram

NOTE: 1. Value I is reset to 0 in the following cases:

• When operation stops.

• When the integral value reset signal is input by multi-function contact input selection. (Any of constants n035 to n039 are

set to 18.

2. The upper limit of value I can be set by constant n090. Increase the value of constant n090 to upgrade control capability by integration. If the control system vibrates and it cannot be stopped by adjusting the integral time or output lag filter time, etc., decrease the setting of constant n090.

3. PID Control can be canceled by a multi-function contact input signal. By setting any of constants n035 to n039 to 19, and by

closing the contact during running, PID Control is disabled and the intended value signal itself is used as a frequency reference signal.

6.9 Energy Saving Control

efesotomasyon.com - Control Techniques,emerson,saftronics -ac drive-servo motor

To enable Energy Saving Control, set energy saving selection (n095) to 1.

Setting Description

0 Energy saving is disabled 1 Energy saving is enabled

Since the constants used in the Energy Saving Control mode have been preset at the factory to the optimum values prior to shipment, it is not necessary to adjust them under normal operation. If your motor characteristics differ greatly from those of Saftronics standard motors, refer to the following description to change the constants.

6.9.1. Energy Saving Control Mode

§ Energy Saving Gain K2 (n096)

Use this energy saving gain when running in the Energy Saving Control mode to calculate the voltage at which motor efficiency will be greatest, and set it as the output voltage reference. This value is preset at the factory to the Saftronics standard motor value prior to shipment. As the energy saving gain increases, output voltage increases also.

§ Energy Saving Voltage Lower Limit (n097, n098)

Sets the output voltage lower limit. If the voltage reference value calculated in the Energy Saving Control mode is smaller than the specified lower limit, this lower limit value is output as the voltage reference value. The lower limit value is set in order to prevent stalling at light loads. Set voltage limits at 6Hz and 60Hz; a value obtained by linear interpolation should be set to any limit values other than at 6Hz or 60Hz. Setting is made as a percentage of motor rated voltage.

Chapter 6: Programming Features

∗ For 400 V class, the value is twice that of 200 V class.

Figure 50 Energy Saving Voltage Lower Limit

6.9.2. Energy Saving Tuning

In the Energy Saving Control mode, the optimum voltage is calculated according to load power, and the voltage is supplied to the load. However, the set constant may vary due to temperature variations or using other manufacturers’ motors, therefore, the optimum voltage may not be supplied in some cases. Automatic tuning controls voltage so that highly efficient operation is maintained.

§ Voltage Limit of Tuning (n100)

Limits the range to control voltage by tuning. Setting is made in a percentage of motor rated voltage. By setting this value to 0, turning is disabled.

§ Step Voltage of Tuning (n100, n101)

Sets voltage variation width of one tuning cycle. Setting is made in a percentage of motor rated voltage. By increasing this value, the rotating speed variation becomes larger. This voltage variation width is set when starting tuning voltage is 100% and motor rated voltage is 5%. Values obtained by linear interpolation are set to any voltage values other than these values.

6.10 MEMOBUS Control

FP5/GP5 can perform serial transmission by using a Programmable Controller (PLC) and MEMOBUS communication. MEMOBUS is composed of one master PLC and 1 to 31 (maximum) slave units (FP5/GP5). In signal transmission (serial transmission) between the master and slaves, the master always starts transmission and the slaves respond to it.

The master performs signal transmission with one slave at a time. Therefore, address numbers are assigned to each slave in advance and the master specifies a number to perform signal transmission. The slave which receives the command from the master executes the function and returns the response to the master.

• Synchronization

• Transmission parameter

• Protocol

• Maximum number of units

6.10.2. Data to be Sent/Received by Communication

Data to be sent/received by communication are RUN commands, frequency reference, fault contents, Inverter status and constant setting/reading.

§ Operation Mode Selection (n002)

Select the RUN command and frequency reference input method in constant n002. To provide a RUN command and frequency reference by communication, set this constant to settings 4 to 8. Also, without regard to this selection, monitoring of running status, constant setting/reading, fault reset and multi-function input command from the PLC are enabled. The multi-function input command becomes OR with the command input from control circuit Terminals S2 to S6.

§ MEMOBUS Frequency Reference Unit (n105)

The frequency reference units from the PLC and in the frequency reference and output frequency monitors (by communication) are selected. The output frequency resolution of the FP5/GP5 is 0.1 Hz. Even if the frequency reference unit is changed to 0.01 Hz in constant n105, the value in the hundredth digit of 0.01 Hz of the received frequency reference is rounded off internally. When 30000/100% in units of 0.1% is selected, the value is rounded off in the same way.

§ MEMOBUS Slave Address (n106)

The slave address number is set. It is necessary to set the address number so that it will not overlap with the address number of another slave connected on the same transmission line.

NOTE: To change the values set in constants n106 to n108 and enable new settings, it is necessary to turn OFF the power supply, and

then turn it ON again.

8.1 Fault Diagnosis and Corrective Actions

§ When the FP5/GP5 detects a fault, the fault is displayed on the Digital Operator and activates the fault contact output and the

motor coasts to a stop. Check the cause in the table below and take the corrective actions.

§ If the inspections or corrective actions described cannot solve the problem, contact your Saftronics representative immediately.

§ To restart, turn ON the reset input signal or press the RESET key or shut OFF the main circuit power supply once, to reset the

stop status.

§ To change the setting of a constant during fault display, first press the DSPL key to call up the monitor display. Then press

DSPL and ENTER keys simultaneously to enter PRGM mode.

NOTE: When a FWD or REV RUN command is input, the Inverter does not receive a fault reset signal. Make sure to reset after turning

OFF the FWD or REV RUN command.
