6.0 INSTALLATION

SCD drives are intended for inclusion within other equipment, by professional electrical installers. They are not intended for stand-alone operation.

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 AC TECHNOLOGY FOR MORE INFORMATION ON THE SUITABILITY OF A DRIVE TO A PARTICULAR ENVIRONMENT.

SCD 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 on each side and 2 inches on the top and bottom for units rated up to 5 HP (3.7 kW). For units rated 7.5 - 25 HP (5.5 - 18.5 kW), maintain at least 2 inches on each side and 4 inches 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 5.0 - SCD 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.

NOTE!

WARNING!

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

6.1 INSTALLATION AFTER A LONG PERIOD OF STORAGE

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.

WARNING!

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.

6.2 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:

“AC Technology Corporation inverter products are sold with no warranty of fitness for a particular purpose or warranty of suitability for use with explosion proof motors. AC Technology 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."

7.0 INPUT AC POWER REQUIREMENTS

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 15.0 - 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 - 25 HP (5.5 -

18.5 kW), 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.

WARNING!

7.1 INPUT VOLTAGE RATINGS

SD200 Series drives are rated for 208/240 Vac, three phase, 50-60 Hz input. The drive will function with input voltages of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.

SD200Y Series drives are rated for 208/240 Vac, single or three phase, 50-60 Hz input. The drive will function with input voltage of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.

SD400 Series drives are rated for 400/480 Vac three phase, 50-60 Hz input. The drive will function with input voltages of 400 to 480 Vac (+10%, -15%), at 48 to 62 Hz.

SD500 Series drives are rated for 480/590 Vac, three phase, 50-60 Hz input, and will function with input voltages of 480 to 590 Vac (+10%, -15%), at 48 to 62 Hz.

NOTE: Parameter 01 - LINE VOLTAGE SELECTION must be programmed according to the applied input voltage. See Section 15.0 - DESCRIPTION OF PARAMETERS.

7.2 INPUT FUSING AND DISCONNECT REQUIREMENTS

A circuit breaker or a disconnect switch with fuses must be provided in accordance with the National Electric Code (NEC) and all local codes. Refer to the following tables for proper fuse/circuit breaker ratings and wire sizes.

8.0 POWER WIRING

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.

Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for input power, output power, and DC Bus wiring.

The input power, output power, and DC Bus terminals must be tightened to a torque of 4.5 lb-in (0.5 Nm).

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.

8.1 WIRING FOR SINGLE PHASE OR THREE PHASE INPUT

If the drive is rated for single and three phase input (SD200Y 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.

WARNING!

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.

WARNING!

Do not connect incoming AC power to output terminals T1, T2, or T3. Severe damage to the drive will result.

NOTES:

1. WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL APPLICABLE LOCAL CODES.

2. Motor wires MUST be run in a separate steel conduit away from control wiring and incoming AC power wiring.

3. Do not install contactors between the drive and the motor without consulting AC Technology for more information. Failure to do so may result in drive damage.

4. Use only UL and CSA listed and approved wire.

5. Minimum wire voltage ratings: 300 V for 208 and 240 Vac systems, and 600 V for 400, 480, and 590 Vac systems.

6. 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.

7. Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for input power, output power, and DC Bus wiring.

VOLTAGE

10.0 CONTROL WIRING

10.1 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.

Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for control wiring, and torque the control terminals to 2 lb-in (0.2 Nm). Be careful not to overtorque the control 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.

10.2 TB-2 AND TB-4

The TB-2 terminal is the circuit common for the analog input and analog output functions. If necessary TB-2 may be connected to chassis ground.

The TB-4 terminal is the reference for all of the digital inputs (TB-1, 12, 13A, 13B, 13C). On standard SCD drives, TB-4 is at zero volt potential. Therefore, the digital inputs are active-low.

10.3 SURGE SUPPRESION 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.

10.4 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 11.0 - SCD CONTROL WIRING DIAGRAMS

10.5 SPEED REFERENCE SIGNALS

The drive allows for three analog speed reference inputs: SPEED POT Connect the wiper of a speed pot (rated 2.5kΩ up to 10kΩ) to terminal TB-5/25, and

0-10 VDC Wire the positive to terminal TB-5/25 and the negative to terminal TB-2. TB-5/25

4-20 mA Wire the positive to terminal TB-5/25 and the negative to terminal TB-2. TB-5/25

connect the high and low end leads to terminals TB-11 and TB-2, respectively.

input impedance is 120 kilohms when programmed for 0-10 VDC input.

input impedance is 100 ohms when programmed for 4-20 mA.

NOTE: When the drive is powered down, the input impedance of terminal TB-5/25 becomes 57 kilohms. If TB-5/25 was programmed as a 4-20 mA input, the 4-20 mA source will suddenly encounter a high input impedance.

10.6 SPEED REFERENCE SELECTION

If only one speed reference is required, set Parameter 05 - STANDARD SPEED SOURCE to the desired speed reference. The selections are: KEYPAD (the ! and " buttons on the front of the drive), PRESET SPEED #1 (Parameter 31), a 0-10 VDC signal, or a 4-20 mA signal.

If multiple speed references are required, terminals 13A, 13B, and 13C can be programmed to select other speed references in addition to the STANDARD SPEED SOURCE (Parameter 05). When the TB-13 terminal is closed to TB-4, the drive will follow the selected speed reference. If a speed reference is not selected using TB-13A, 13B, or 13C, speed control will default back to the source programmed in STANDARD SPEED SOURCE.

When using the DeviceNet interface, speed reference selection can be done as described above. However, DeviceNet can override the selected speed reference and directly control the drive speed. Refer to Appendix B - DEVICENET CONTROL for more information.

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-4. Refer to Parameters 31-37 in Section 15.0 - 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-4 to JOG, and open the contact to STOP.

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.

WARNING!

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-4 will cause the speed setpoint to decrease until the contact is opened. Closing TB-13C to TB-4 will cause the speed setpoint to increase until the contact is opened. The INCREASE FREQ function will only operate while the drive is running.

NOTE: If TB-13A, TB-13B, and TB-13C are all programmed to select speed references, and two or three of the terminals are closed to TB-4, the higher terminal has priority and will override the others. For example, if TB-13A is programmed to select 0-10VDC, and TB-13C is programmed to select PRESET SPEED #3, closing both terminals to TB-4 will cause the drive to respond to PRESET SPEED #3, because TB-13C overrides TB-13A.

The exception to this is the MOP function, which requires the use of TB-13B and TB-13C. This leaves TB-13A to be used for some other function. If TB-13A is programmed for a speed reference, and TB-13A is closed to TB-4, TB-13A will override the MOP function.

10.7 ANALOG OUTPUT SIGNALS

Terminal TB-30 can provide a 0-10 VDC or a 2-10 VDC signal proportional to output frequency or load, and TB-31 can provide the same signals proportional to load only. The 2-10 VDC signal can be converted to a 4-20 mA signal using a resistor in series with the signal such that the total load resistance is 500 Ohms. Refer to Parameters 08 and 09 in Section 15.0 - DESCRIPTION OF PARAMETERS.

NOTE: These analog output signals cannot be used with “loop-powered” devices that derive power from a 4-20 mA signal.

10.8 DRIVE STATUS DIGITAL OUTPUTS

There are two open-collector outputs at terminals TB-14 and TB-15. The open-collector circuits are current-sinking types rated at 30 VDC and 50 mA maximum.

The open-collector outputs can be programmed to indicate one of various drive status conditions. Refer to Parameters 06 and 13 in Section 15.0 - DESCRIPTION OF PARAMETERS.

The diagram below illustrates how the 12 VDC power supply at TB-11 can be used with the opencollector output to drive an external relay:

2. If reverse direction is also required, ROTATION DIRECTION (Parameter 17) must be set to

FORWARD AND REVERSE (02), and TB-13A (Parameter 10) must be set to START REVERSE (06). If reverse direction is not required, TB-12 must be wired directly to TB-4.

3. For 0-10 VDC or 4-20 mA speed control, use one of the following methods:

1. Program one of the TB-13 terminals (13A, 13B, or 13C) for 0-10 VDC (02) or 4-20 mA (03). When that TB-13 terminal is closed to TB-4, the drive will respond to the selected speed reference signal. If that TB-13 terminal is not closed to TB-4, the drive will respond to the speed control source selected in Parameter 05 - STANDARD SPEED SOURCE. This method must be used if it is necessary to toggle between two speed sources.

2. Program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC (03) or 4-20 mA (04). This method is preferable if only one speed source is required, as this method leaves the TB13 terminals free to be used for other functions.

2. Close TB-12 to TB-4 to RUN in forward direction, and open TB-12 to TB-4 to STOP.

3. If reverse direction is also required, ROTATION DIRECTION (Parameter 17) must be set to FORWARD AND REVERSE (02). Close TB-13A to TB-4 to RUN in REVERSE, and open TB13A to TB-4 to STOP. If TB-12 and TB-13A are both closed to TB-4, the drive will STOP.

4. For 0-10 VDC or 4-20 mA speed control, use one of the following methods:

1. Program one of the TB-13 terminals (13A, 13B, or 13C) for 0-10 VDC (02) or 4-20 mA (03).

When that TB-13 terminal is closed to TB-4, the drive will respond to the selected speed reference signal. If that TB-13 terminal is not closed to TB-4, the drive will respond to the speed control source selected in Parameter 05 - STANDARD SPEED SOURCE. This method must be used if it is necessary to toggle between two speed reference sources.

2. Program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC (03) or 4-20 mA (04).

NOTES:

1. Momentarily close TB-12 to TB-4 to START the drive in forward direction, and momentarily

open TB-1 to TB-4 to STOP the drive.

2. If reverse direction is also required, ROTATION DIRECTION (Parameter 17) must be set to

FORWARD AND REVERSE (02), and TB-13A (Parameter 10) must be set to START REVERSE (06). If the FWD/REV switch is changed while the drive is running, the drive will not change direction until the START button is pushed. If reverse direction is not required, the other side of the START pushbutton must be wired directly to TB-12.

3. For 0-10 VDC or 4-20 mA speed control, use one of the following methods:

NOTES:

1. Program the PRESET SPEEDS (Parameters 31-37) to the desired values.

2. Program TB-13A (Parameter 10) to PRESET SPEED #1 (04), TB-13B (Parameter 11) to PRESET SPEED #2 (04), and TB-13C (Parameter 12) to PRESET SPEED #3 (04). To select a preset speed, close the appropriate TB-13 terminal(s) to TB-2 (refer to Parameters 31-37 for the Preset Speed Activation table).

3. If reverse rotation is also required, TB-13A cannot be used as a PRESET SPEED SELECT. TB13A must be programmed to select RUN REVERSE (05) or START REVERSE (06), leaving only TB-13B and TB-13C to select preset speeds.

4. For speed pot control, program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC (03). If none of the preset speeds are selected (all of the TB-13 terminals are open), the drive will respond to the speed pot.

12.0 INITIAL POWER UP AND MOTOR ROTATION

DO NOT connect incoming AC power to output terminals T1, T2, and T3! Severe damage to the drive will result. Do not continuously cycle input power to the drive more than once every two minutes. Damage to the drive will result.

Hazard of electrical shock! Wait three minutes after disconnecting incoming power before servicing drive. Capacitors retain charge after power is removed.

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!

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.

Before attempting to operate the drive, motor, and driven equipment, be sure all procedures pertaining to installation and wiring have been properly followed.

Disconnect the driven load from the motor. Verify that the drive input terminals (L1, L2, and L3) are wired to the proper input voltage per the nameplate rating of the drive.

WARNING!

Energize the incoming power line. The LED display will flash a three digit number (322 in the example below) that identifies the parameter version contained in the drive. The display should then read “- - -”, which indicates that the drive is in a STOP condition. This is shown below:

Apply input power Display flashes parameter

version (300-399) Display then reads "- - -"

Follow the procedure below to check the motor rotation. This procedure assumes that the drive has been powered up for the first time, and that none of the parameters have been changed.

1. Use the ! button to decrease the speed setpoint to 00.0 Hz. The left decimal point will illuminate as the speed setpoint is decreased. If the ! button is held down, the speed setpoint will decrease by tenths of Hz until the next whole Hz is reached, and then it will decrease by one Hz increments. Otherwise, each push of the ! button will decrease the speed setpoint by a tenth of a Hz.

Once 00.0 Hz is reached, the display will toggle between “00.0” and “- - -”, which indicates that the drive is in a STOP condition with a speed setpoint of 00.0 Hz.

2. Give the drive a START command. This can be done using one of several wiring methods described in Section 11.0 - SCD CONTROL WIRING DIAGRAMS. Once the START command is issued, the display will read “00.0”, indicating that the drive is in a RUN condition with a speed setpoint of 00.0 Hz.

3. Use the " button to increase the speed setpoint until the motor starts to rotate. The left decimal point will light as the speed setpoint is increased. If the " button is held down, the speed setpoint will increase by tenths of Hz until the next whole Hz is reached, and then it will increase by one Hz increments. Otherwise, each push of the button will increase the speed setpoint by a tenth of a Hz.

4. If the motor is rotating in the wrong direction, give the drive a STOP command and remove power from the drive. Wait three minutes for the bus capacitors to discharge, and swap any two of the motor wires connected to T1, T2, and T3.

NOTE: The drive is phase insensitive with respect to incoming line voltage. This means that the drive will operate with any phase sequence of the incoming three phase voltage. Therefore, to change the motor rotation, the phases must be swapped at the drive output terminals or at the motor.

13.0 PROGRAMMING THE SCD DRIVE

The drive may be programmed by one of three methods: using the three buttons and 3-digit LED display on the front of the drive, programming the Electronic Programming Module (EPM) using the optional EPM Programmer, and through the DeviceNet interface (refer to Appendix B). This section describes programming the drive using the buttons and display, which are shown below:

BUTTONS

Mode

To enter the PROGRAM mode to access the parameters, press the Mode button. This will activate the PASSWORD prompt (if the password has not been disabled). The display will read “00” and the upper right-hand decimal point will be blinking, as shown below:

Press Mode

Display reads "00"

Upper right decimal point blinks

Use the " and ! buttons to scroll to the password value (the factory default password is “225”) and press the Mode button. Once the correct password value is entered, the display will read "P01", which indicates that the PROGRAM mode has been accessed at the beginning of the parameter menu (P01 is the first parameter). This is shown below:

Use " and ! to scroll to the password value

Press Mode to enter password

DISPLAY

Parameter menu is accessed at the first parameter

NOTE: If the display flashes “Er”, the password was incorrect, and the process to enter the password must be repeated.

Use the " and ! buttons to scroll to the desired parameter number. In the example below, Parameter 19 is being displayed, which is the ACCELERATION TIME of the drive:

Use " and ! to scroll to the desired parameter number (the example is Parameter 19 - ACCELERATION TIME)

Once the desired parameter number is found, press the Mode button to display the present parameter setting. The upper right-hand decimal point will begin blinking, indicating that the present parameter setting is being displayed, and that it can be changed by using the " and ! buttons.

Press Mode to display present parameter setting (example setting is 20.0)

Upper right decimal point blinks

Use " and ! to change setting (example setting changed to 30.0)

Press Mode to store new setting

Pressing the Mode will store the new setting and also exit the PROGRAM mode. To change another parameter, press the Mode key again to re-enter the PROGRAM mode (the parameter menu will be accessed at the parameter that was last viewed or changed before exiting). If the Mode key is pressed within two minutes of exiting the PROGRAM mode, the password is not required access the parameters. After two minutes, the password must be entered in order to access the parameters again.

13.1 SETTING VALUES IN TENTHS OF UNITS ABOVE 100

Parameter settings and the keypad speed command can always be adjusted in tenths of unit increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or tenths of units, depending on the setting of Parameter 16 - UNITS EDITING.

If Parameter 16 - UNITS EDITING is set to WHOLE UNITS (02), parameter values and the keypad speed command can only be adjusted by whole unit increments above 100. For example, Parameter 19 - ACCELERATION TIME could not be set to 243.7 seconds. It could only be set to 243 or 244 seconds. Likewise, the keypad speed command (set using the " and ! buttons) could not be set to

113.4 Hz. It could only be set to 113 or 114 Hz.

If, however, Parameter 16 - UNITS EDITING is set to TENTHS OF UNITS (01), parameter values and the keypad speed command can be adjusted in tenths of unit increments up to a value of 1000 (above 1000, whole unit increments only). Each push of the " or ! button will adjust the value by one tenth of a unit. If the " or ! button is pressed and held, the value will increment by tenths of units until the next whole unit is reached, and then the value will increment by whole units.

When a value above 100 is being adjusted by tenths of units, the value is shifted to the left by one digit so that the tenths portion of the value can be displayed. This results in the first digit (reading from left to right) of the value disappearing from the display. Also, the lower decimal point will blink to indicate that the actual value is above 100. Once the value is no longer being adjusted, the value will shift back to the right and the tenths portion of the value will disappear.

In the example below, Parameter 19 - ACCELERATION TIME is presently set to 243.0 seconds, and is being increased to 243.7 seconds.

Go to Parameter 19 and press Mode to see present setting ("243" seconds)

Upper right decimal point blinks

Press " button to see tenths portion Value shifts to the left ("2" disappears)

Upper right decimal point and lower decimal point blink

Press " button to scroll up to "43.7"

Press Mode to store new value
