1.5 Safety Information

GENERAL Some parts of Lenze AC Tech controllers can be electrically live and some surfaces can be hot.

Non-authorized removal of the required cover, inappropriate use, and incorrect installation or operation creates the risk of severe injury to personnel or damage to equipment.

All operations concerning transport, installation, and commissioning as well as maintenance must be carried out by qualiﬁed, skilled personnel who are familiar with the installation, assembly, commissioning, and operation of variable frequency drives and the application for which it is being used.

The safety information given in these Operating Instructions is deﬁned herein.

Signal Word! (characterizes the severity of the danger) Note (describes the danger and informs on how to proceed)

Icon Signal Words

Warning of hazardous electrical voltage

Warning of a general danger

Warning of damage to equipment

Information Note Designates a general, useful note.

INSTALLATION Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and do not change any insulation distances during transport, handling, installation or maintenance.

Do not touch any electronic components or contacts. This drive contains electrostatically sensitive components, which can easily be damaged by inappropriate handling. Static control precautions must be adhered to during installation, testing, servicing and repairing of this drive and associated options. Component damage may result if proper procedures are not followed.

The SCF drive is considered a component for integration into a machine or process. It is neither a machine nor a device ready for use in accordance with European directives (reference machinery directive and electromagnetic compatibility directive). It is the responsibility of the end user to ensure that the machine meets the applicable standards.

ELECTRICAL CONNECTION

When working on live drive controllers, applicable national safety regulations must be observed.

The electrical installation must be carried out according to the appropriate regulations (e.g. cable cross-sections, fuses, protective earth [PE] connection). While this document does make recommendations in regards to these items, national and local codes must be adhered to.

Integral solid state protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any additional local codes. The use of fuses or circuit breakers is the only approved means for branch circuit protection.

DANGER! Warns of impending danger.

WARNING! Warns of potential, very hazardous situations.

STOP! Warns of potential damage to material and equipment.

Consequences if disregarded: Death or severe injuries.

Consequences if disregarded: Damage to the controller/drive or its environment.

If you observe it, handling the drive is made easier.

1 Safety Information

The documentation contains information about installation in compliance with EMC (shielding, grounding, ﬁlters and cables). These notes must also be observed for CE-marked controllers.

The manufacturer of the system or machine is responsible for compliance with the required limit values demanded by EMC legislation.

APPLICATION

The drive must not be used as a safety device for machines where there is a risk of personal injury or material damage. Emergency Stops, over-speed protection, acceleration and deceleration limits, etc must be made by other devices to ensure operation under all conditions.

The drive does feature many protection devices which are aimed at protecting the drive and the driven equipment by generating a fault and shutting the drive and motor down by removing power. Mains power variances can also result in shutdown of the drive. When the fault condition disappears or is cleared, the drive can be conﬁgured to automatically restart, it is the responsibility of the user and/ or OEM and/or integrator to ensure that the drive is conﬁgured for safe operation.

Safety Information 1

This drive has been tested by Underwriters Laboratory (UL) and is an approved component in compliance with UL508 Safety Standard.

• Suitable for use on a circuit as described in Section 3.2 of this manual.

Warnings!

This drive must be installed and conﬁgured in accordance with both national and international standards. Local codes and regulations take precedence over recommendations provided in this and other Lenze AC Tech documentation.

• Use minimum 75 °C copper wire only, except for control circuits.

• For control circuits, use wiring suitable for NEC Class 1 circuits only.

• Shall be installed in a pollution degree 2 macro-environment.

DANGER!

Risk of Electric Shock! Capacitors retain charge for approximately 180 seconds after power is removed. Disconnect incoming power and wait at least 3 minutes before touching the drive.

DANGER!

Risque de choc électrique! Les condensateurs restent sous charge pendant environ 180 secondes après une coupure de courant. Couper l’alimentation et patienter pendant au moins 3 minutes avant de toucher l’entraînement.

WARNING!

The opening of branch-circuit protective device may be an indication that a fault has been interrupted. To reduce the risk of ﬁre or electric shock, current carrying parts and other components of the controller should be examined and replaced if damaged.

WARNING!

Le déclenchement du dispositif de protection du circuit de dérivation peut être dû à une coupure qui résulte d’un courant de défaut. Pour limiter le risque d'incendie ou de choc électrique, examiner les pièces porteuses de courant et les autres éléments du contrôleur et les remplacer s'ils sont endommagés.

3 Installation

3.1 Standard Installation

NOTE

SCF Series drives are intended for inclusion within other equipment, by professional electrical installers according to EN 61000-3-2. They are not intended for stand-alone operation

WARNING!

Drives must NOT be installed where subjected to adverse environmental conditions such as: combustible, oily, or hazardous vapors or dust; excessive moisture or dirt; vibration; excessive ambient temperatures. Consult Lenze Americas for more information on the suitability of a drive to a particular environment.

SCF models are suitable for UL pollution degree 2 environment only, and MUST be installed in an electrical enclosure which will provide complete mechanical protection and will maintain the internal temperature within the drive’s ambient operating temperature rating. All drive models MUST be mounted in a vertical position for proper heatsink cooling.

Maintain a minimum spacing around the drive of at least 1 inch (25 mm) on each side and 2 inches (50 mm) on the top and bottom for units rated up to 5 HP (3.7 kW). For units rated 7.5 - 30 HP (5.5 - 22 kW), maintain at least 2 inches (50 mm) on each side and 4 inches (100 mm) on the top and bottom. Allow more spacing if the drive is mounted next to other heat-producing equipment. Do not mount drives above other drives or heat producing equipment. Fans or blowers should be used to insure proper cooling in tight quarters.

In order to properly size an enclosure, the heat generated by the drive(s) must be known. Refer to the HEAT LOSS columns in Section 2.4 - SCF Ratings. The STD column is for standard units, and the THRU column is for through-hole mount units (drives with the through-hole mount option still generate some heat inside the enclosure that must be taken into account). An enclosure manufacturer can then determine the required enclosure size based on the total heat generated inside the enclosure (from the drive(s) and other heat sources), the maximum allowable temperature inside the enclosure, the maximum ambient temperature outside the enclosure, and the enclosure properties.

The SCF Series is UL approved for solid state motor overload protection. Therefore, a separate thermal overload relay is not required for single motor applications.

3.1.1 Installation After a Long Period of Storage

STOP!

Severe damage to the drive can result if it is operated after a long period of storage or inactivity without reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding three years (due to storage, etc), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive leakage current . This can result in premature failure of the capacitors if the drive is operated after such a long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply input power to the drive for 8 hours prior to actually operating the motor.

Installation 3

3.1.2 Explosion Proof Applications

Explosion proof motors that are not rated for inverter use lose their certiﬁcation when used for variable speed. Due to the many areas of liability that may be encountered when dealing with these applications, the following statement of policy applies:

“Lenze AC Tech Corporation inverter products are sold with no warranty of ﬁtness for a particular purpose or warranty of suitability for use with explosion proof motors. Lenze AC Tech Corporation accepts no responsibility for any direct, incidental or consequential loss, cost, or damage that may arise through the use of its AC inverter products in these applications. The purchaser expressly agrees to assume all risk of any loss, cost, or damage that may arise from such application."

3.2 Input AC Power Requirements

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Disconnect incoming power and wait until the voltage between terminals B+ and B- is 0 VDC before servicing the drive.

The input voltage must match the nameplate voltage rating of the drive. Voltage ﬂuctuation must

not vary by greater than 10% overvoltage or 15% undervoltage.

NOTE

Drives with dual input voltage ratings must be programmed for the proper supply voltage (refer to Parameter 01 - LINE VOLTAGE SELECTION in Section 4.4 - Description of Parameters).

The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical amperes at 5 HP (3.7 kW) and below, and 18,000 RMS symmetrical amperes at 7.5 HP (5.5 kW) and above, at the drive’s rated voltage.

If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating of the

drive(s), an isolation transformer or 2-3% input line reactor must be added to the line side of the

drive(s).

Three phase voltage imbalance must be less than 2.0% phase to phase. Excessive phase to phase

imbalance can cause severe damage to the drive’s power components.

Motor voltage should match line voltage in normal applications. The drive’s maximum output voltage will equal the input voltage. Use extreme caution when using a motor with a voltage rating which is different from the input line voltage.

NOTE

• Applicable national and local electrical codes take precedence over

recommendations in these tables.

• Use UL Class CC fast-acting, current limiting type fuses. Select fuses with low I

T values, rated at 200,000 AIC. Recommended fuses are Bussman KTK-R, JJN, and JJS. Similar fuses with equivalent ratings by other manufacturers may also be acceptable.

WARNING!

This product can cause a DC current in the protective conductor. Where a residual current device (RCD) is used for protection in case of direct or indirect contact, only an RCD of Type B is allowed on the supply side of this product. Otherwise, another protective measure shall be applied, such as separation from the environment by double or reinforced insulation, or isolation from the supply system by a transformer.

Observe the following when using RCDs:

1. Only install the RCD between the supply mains and drive controller.

2. The RCD can be activated by:

- capacitive leakage currents between the cable screens during operation (especially with long, screened motor cables)

- connecting several drives to the mains at the same time

- additional RFI ﬁlters

3 Installation

3.2.4 Installation According to EMC Requirements

The SCF Series can be installed to meet the European standards for Electromagnetic Compatibility (EMC) requirements. These requirements govern the permissible electromagnetic emissions and immunity, both radiated and conducted, of a drive system.

The EMC requirements apply to the ﬁnal installation in its entirety, not to the individual components used. Because every installation is different, the recommended installation should follow these guidelines as a minimum. Additional equipment (such as ferrite core absorbers on power conductors) or alternative wiring practices may be required to meet conformance in some installations.

Filter: The input to the drive (or group of drives) must include a ﬁlter to reduce the electrical noise reﬂected back to the AC Line. The SCM can be installed to meet the industrial standards set by the EU, EN 61800-3 for conducted emissions and EN 55011 for radiated emissions to class A compliance when installed with an appropriately installed external line ﬁlter.

EMC Compliance with EN 61800-3/A11

Installation: Shielded cable must be used for all control and power cables and exposed wiring must be kept as short as possible.

3.3 Power Wiring

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Disconnect incoming power and wait until the voltage between terminals B+ and B- is 0 VDC before servicing the drive.

Note drive input and output current ratings and check applicable electrical codes for required wire type and size, grounding requirements, over-current protection, and incoming power disconnect, before wiring the drive. Size conservatively to minimize voltage drop.

Refer to Section 3.4 - SCF Power Wiring Diagram for information on torque and wire stripping requirements for power wiring.

Input fusing and a power disconnect switch or contactor MUST be wired in series with terminals L1, L2, and L3 for three phase input models. For 208/240 Vac single phase input models, use terminals L1 and L2. This disconnect must be used to power down the drive when servicing, or when the drive is not to be operated for a long period of time, but should not be used to start and stop the motor.

Repetitive cycling of a disconnect or input contactor (more than once every two minutes) may cause damage to the drive.

18 Lenze 13466146 EDBSF01 v24 EN

Installation 3

3.3.1 Wiring for Single Phase or Three Phase Input

If the drive is rated for single and three phase input (SF200Y models), wire to terminals L1 and L2 for single phase input, or wire to terminals L1, L2, and L3 for three phase input.

If the drive is rated for three phase input, wire the input to terminals L1, L2, and L3.All three power output wires, from terminals T1, T2, and T3 to the motor, must be kept tightly bundled and run in a separate conduit away from all other power and control wiring.

It is not recommended to install contactors or disconnect switches between the drive and motor. Operating such devices while the drive is running can potentially cause damage to the drive's power components. If such a device is required, it should only be operated when the drive is in a STOP state. If there is potential for the device to be opened while the drive is running, the drive must be programmed for COAST to stop (see Parameter 4 - STOP METHOD), and an auxiliary contact on the device must be interlocked with the drive's run circuit. This will give the drive a stop command at the same time the device opens, and will not allow the drive to start again until the device is closed.

DO NOT connect incoming AC power to output terminals T1, T2, T3, or terminals B+, B-! Severe damage to the drive will result.

NOTE

• WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL APPLICABLE LOCAL

CODES.

• Motor wires MUST be run in a separate steel conduit away from control wiring and

incoming AC power wiring.

• Do not install contactors between the drive and the motor without consulting Lenze

AC Tech Corporation for more information. Failure to do so may result in drive damage.

• Use only UL and CSA listed and approved wire.

• Minimum wire voltage rating is 300 V for 120, 208, and 240 Vac systems, and 600 V

for 400 and 480 Vac systems.

• Wire gauge must be based on a minimum of 125% of the rated input/output current of the drive, and a minimum 75°C insulation rating. Use copper wire only.

3.5 Control Wiring

3.5.1 Control Wiring vs. Power Wiring

External control wiring MUST be run in a separate conduit away from all other input and output power wiring. If control wiring is not kept separate from power wiring, electrical noise may be generated on the control wiring that will cause erratic drive behavior. Use twisted wires or shielded cable grounded at the drive chassis ONLY. Recommended control wire is Belden 8760 (2-wire) or 8770 (3-wire), or equivalent.

NOTE

Control terminals provide basic isolation (insulation per EN 61800-5-1). Protection against contact can only be assured by additional measures e.g. supplemental insulation.

Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for control wiring, and torque the terminals to 2 lb-in (0.2 Nm). Be careful not to overtorque the terminals, as this will cause damage to the terminal strip. This is not covered under warranty and can only be repaired by replacing the control board.

3.5.2 TB-2: Circuit Common

The TB-2 terminals are used as circuit common for the start/stop, forward/reverse, input select, local/remote, analog input, and analog output functions. There are three TB-2 terminals available on the terminal strip, and they are all internally connected to each other on the main control board. If necessary TB-2 may be connected to chassis ground.

NOTE

TB-2 must be connected to chassis ground when using serial communications.

3.5.3 Surge Suppression on Relays

Current and voltage surges and spikes in the coils of contactors, relays, solenoids, etc, near or connected to the drive, can cause erratic drive operation. Therefore, a snubber circuit should be used on coils associated with the drive. For AC coils, snubbers should consist of a resistor and a capacitor in series across the coil. For DC coils, a free-wheeling or ﬂyback diode should be placed across the coil. Snubbers are typically available from the manufacturer of the device.

3.5.4 Start/Stop Control

There are various control schemes that allow for 2-wire and 3-wire Start/Stop circuits. Refer to the wiring diagrams in Section 3.6 - SCF Control Wiring Diagrams

3.5.5 Speed Reference Signals

The drive allows for three analog speed reference inputs:

SPEED POT Connect the wiper of a speed pot to terminal TB-5, and connect the high and low end

0-10 VD C Wire the positive to terminal TB-5 and the negative to terminal TB-2. TB-5 input impedance

4-20 mA Wire the positive to terminal TB-25 and the negative to terminal TB-2. TB-25 input

leads to terminals TB-6 and TB-2, respectively. The speed pot can be 2.5kΩ up to 10kΩ.

is 120 kilohms.

impedance is 100 ohms.

3.5.6 Speed Reference Selection

If an analog speed reference input is used to control the drive speed, terminal TB-13A, 13B, or 13C (Parameter 10, 11, or 12) may be programmed as the input select for the desired analog input signal. When that TB-13 terminal is then closed to TB-2, the drive will follow the selected analog speed reference input.

If an analog speed reference input is not selected on the terminal strip using TB-13A, 13B, or 13C, speed control will default to STANDARD mode, which is governed by the setting of Parameter 05 -

STANDARD SPEED SOURCE. The STANDARD SPEED SOURCE can be the p and q buttons on the front of the drive, PRESET SPEED #1 (Parameter 31), a 0-10 VDC signal, or a 4-20 mA signal.

0 - 10 VDC and 4 - 20 mA INPUT SIGNALS

TB-13A, TB-13B, and TB-13C can all be programmed to select a 0-10 VDC or 4-20 mA analog speed reference input.

PRESET SPEEDS

TB-13A can be programmed to select PRESET SPEED #1, TB-13B to select PRESET SPEED #2, and TB-13C to select PRESET SPEED #3. There are a total of seven preset speeds, which are activated by different combinations of contact closures between TB-13A, 13B, 13C and TB-2. Refer to Parameters 31-37 in Section 4.4 - Description of Parameters.

JOG

TB-13B can be programmed to select either JOG FORWARD or JOG REVERSE. The Jog speed is set by PRESET SPEED #2. Close TB-13B to TB-2 to JOG, and open the contact to STOP.

WARNING!

When operating in JOG mode, the STOP terminal (TB-1) and the STOP key (on the optional remote keypad) WILL NOT stop the drive. To stop the drive, remove the JOG command.

JOG REVERSE will operate the drive in reverse rotation even if ROTATION DIRECTION (Parameter 17) is set to FORWARD ONLY

NOTE

If the drive is commanded to JOG while running, the drive will enter JOG mode and run at PRESET SPEED #2. When the JOG command is removed, the drive will STOP.

MOTOR OPERATED POT (MOP) / FLOATING POINT CONTROL

TB-13B and TB-13C are used for this function, which controls the drive speed using contacts wired to the terminal strip. Program TB-13B for DECREASE FREQ (05), and program TB-13C for INCREASE FREQ (05). Closing TB-13B to TB-2 will cause the speed setpoint to decrease until the contact is opened. Closing TB-13C to TB-2 will cause the speed setpoint to increase until the contact is opened. The INCREASE FREQ function will only operate while the drive is running.
