the conductors in accordance with Article 310 of the National Electrical Code.
If conductors of a smaller than recommended size are used in parallel to share
current then the conductors should be kept together in as sets i.e. U1, VI, W1
in one conduit and U2, V2, W2 in another. National and local electrical codes
should be checked for possible cable derating factors if more than three power
conductors are run in the same conduit.
Install a molded case circuit breaker (MCCB) between the power source and the
inverter. Size the MCCB to clear the available fault current of the power source.
Installation of inverter systems should conform to the National Electrical Code,
regulations of the Occupational Safety and Health Administration, all national
codes, and all regional or industry codes and standards.
If a secondary Magnetic Contactor (MC) is used between the inverter output
and the load, it should be interlocked so the ST-CC terminals are disconnected
before the output contactor is opened. If the output contactor is used for bypass
operation, it must also be interlocked so that commercial power is never applied
to the inverter output terminals (U,V,W).

4.2 Selection of Main Circuit Wiring Equipment and
Standard Cable Sizes (cont'd)
* The customer supplied Molded Case Circuit Breaker (MCCB) or Magnetic Circuit
Protector (MCP) should be coordinated with the available short circuit current. The units
are rated for output short circuit faults of 5000A (1 - 50 HP), lO.OOOA (51 - 200 HP), and
18,000A (201 - 400 HP) according to the UL 508C "Power Conversion Equipment",
Table 58.2 or CSA Standard C22.2 No.14-M1987 "Industrial Control Equipment"
Table 24. The selection of breakers for this table is in accordance with 1990 NEC
Article 430. The selection of these breakers takes into consideration motor starting
at the low end of the output voltage specifications but does not consider the use of
high efficiency motors.
* For multiple motor applications, the magnetic only MCP should be replaced by a thermal
magnetic MCCB. The MCCB should be sized according to 1.25 X (largest motor Full
Load Amps) + (sum of all other motor Full Load Amps) to meet National Electric Code
(NEC) or Canadian Electrical Code (CEC) requirements. An individual overload relay
must be provided for each motor in multiple motor applications.
** Wire sizing is based upon NEC table 310-16 or CEC Table 2 using 75 deg C cable, an
ambient of 30deg C, cable runs for less than 200 FT., and copper wiring for not more
than three conductors in raceway or cable or earth (directly buried). The customer should
consult the NEC or CEC wire Tables for his own particular application and wire sizing.
TOSHIBA
** For cable runs greater than 200 FT. between the motor and inverter, consult the factory
before installing.
*** Use two parallel conductors instead of a single conductor (this will allow for the proper
wire bending radius within the cabinet). Use separate conduits for routing parallel
conductors. This prevents the need for conductor derating (see note 3 this page).
Use separate conduits for routing incoming power, power

8.0 System Status Monitoring
The inverter operates with varying levels of supply voltage and current. A variable output
frequency of voltage and current is generated to drive the motor load. These input and output
levels of operating voltage and current are continually monitored by the inverter. It also monitors
for over temperature, input and output terminal settings, and condition of the microprocessor
with associated memory elements. These operating settings and variables have a certain value
or "status" associated with them and are used for inverter operation. They can also be monitored
by the operator to show the setup and conditions existing at any time. Three types of status
monitoring are used and explained below.
8.1 Normal Status Monitoring
Normal status monitoring occurs during normal operation. The ST-CC terminal must be
closed to run. The following table shows applicable keys, display, and status conditions
for normal status monitoring. The display values are for factory settings where no trips
or errors occurred. The display will change only if a new value is programmed into the
associated group adjustment range or if trips or errors have occurred. Scrolling occurs
by repeatedly pressing the READ/WRITE key after output frequency is displayed. Trips
or errors that have occurred (up to a total of three), will be displayed in order immediately
after the keypad software version display.

Automatic status monitoring displays abnormal status conditions that can occur during
normal inverter operation. These conditions will cause warnings and error messages
to be displayed but will not cause the inverter to trip. The table below shows these
abnormal conditions and the associated display that will appear. These displays usually
appear during the time that the abnormal condition is occurring and will go away when it
is corrected. The abnormal condition should be corrected as soon as possible.

8.3 Tripped Status Monitoring
Tripped status monitoring displays abnormal status conditions that can occur during
normal inverter operation. The table below shows these abnormal conditions which will
cause the inverter to trip "off" (stop normal operations). They are usually caused by
excessive power dissipation in either the inverter or motor, or by other circuit
abnormalities. A tripped status monitoring display usually appears during the time that
the abnormal condition is occurring and then remains on the display after the inverter
trips off. The inverter will remain off and the tripped status will remain displayed until the
inverter is attended to (reset) by the operator. Most conditions, which cause the inverter
to trip, occur very rapidly and the operator usually will not be aware that the trip
conditions are in process until the inverter has stopped. Each of the trip statuses are
automatically recorded in the non-volatile EEPROM memory of the inverter. An ordered
semi-permanent record of each trip (up to four) is created and can be viewed during the
normal status monitoring "scroll". These recorded trips are viewed immediately after the
keypad's software version, in the order that they occurred, as the READ/WRITE key is
pressed. These trips remain in the memory until replaced by new trips.

terminal input representation is determined by setting the Input Selection function [:l.tb].
Refer to Item 5 on page 7-3 and Terminal Block details on page 5-5. A reading such as
the example below indicates that terminal ST-CC has a closed contact across it. If input
terminal select [:l.tb]=3 then terminal JOG(SS2)=JOG, terminal AD2(SS3)=AD2, and
they are both open contact.

8.5Output Terminal Status Code
The table below shows the status codes of the open collector transistor outputs.
RCH(UL) and LOW(LL) are multi-functional terminals. The correct terminal output
representation is determined by setting the Output Selection function [:0.tb]. Refer to
Item 6 on page 7-3 and Terminal Block details on page 5-5. If output terminal select
[:0.tb]=2 then terminal RCH(UL)=RCH and terminal LOW(LL)=LL. A reading such as
the example below indicates that terminals RCH and LL are "on" (collector shorted to
ground).
RCH: Output frequency is within the set reach frequency range or acc/dec is complete.
LOW: Output frequency is equal to or greater than low speed frequency.
UL: Output frequency has reached the upper limit frequency (UL).
LL: Output frequency is equal to or greater than the lower limit frequency (LL).

the maximum frequency (FH) set by function [:FH]. Setting this time to low can
cause undue stress and over current tripping of the drive.
DECELERATION TIME #1 (ITEM 2) - Sets the time required to decelerate from
maximum frequency (FH) to OHz. Setting this time to low can cause undue stress
and over voltage tripping of the drive.
UPPER FREQUENCY LIMIT (ITEM 3) - Sets the upper frequency limit of applications.
The inverters frequency can be increased up to this upper limit and cannot be increased
any further. The value of the maximum safe frequency (FH) must be equal to or
greater than the upper frequency limit.
TOSHIBA
LOWER FREQUENCY LIMIT (ITEM 4) - Sets the lower frequency limit of applications.
The inverters frequency can be decreased down to this lower limit and cannot be
decreased any further without stopping or resetting the lower limit.
TERMINAL IV REFERENCE POINT# 1 (ITEM 5) - Sets the percentage of the input
signal on terminal IV which is used to reference the # 1 output frequency (PI) designated
by function [F-P1]
POINT # 1 OUTPUT FREQUENCY (ITEM 6) - Sets the output frequency used for
reference point function [FP-1].
TERMINAL IV REFERENCE POINT # 2 (ITEM 7)- Sets the percentage of the input
signal on terminal IV which is used to reference the # 2 output frequency designated
by function [F-P2]
POINT # 2 OUTPUT FREQUENCY (ITEM 8) - Sets the output frequency used for
reference point [FP-2].
ELECTRONIC THERMAL PROTECTION LEVEL (ITEM 9) - Sets the thermal overload
detection level to match the ratings and characteristics of the motor being used (10 to
100% of rated output current). The inverter can run at 110% continuously and may
cause unnecessary motor overheating unless this compensation is used.
STALL PREVENTION ACTIVATION LEVEL (ITEM 10) - Sets the activation level of the
stall protection function (90 to 120% of rated output current). When the stall level is
reached the inverter begins a soft stall procedure by lowering the frequency and voltage
to prevent overcurrent tripping. Once the soft stall procedure starts the output current
will be clocked. If output current is not reduced within a specified time a fault will occur.
The soft stall function is particularly useful Is situations where load current decreases
as the revolution speed decreases (fan and pump equipment). This function is activated
through the Electronic Thermal Protection Select (:SEL4). Instantaneous trip current
limits are factory set and are dependent upon inverter size as well as the motor
ripple current.

USER GROUP PARAMETERS
MAXIMUM FREQUENCY (ITEM 1) - This parameter sets the output frequency to a
maximum value. It is very important that this factory setting not be changed without
first checking the maximum operating speed of the motor and load equipment.
Overspeeding of the motor can cause serious damage to the motor and/or the
driven load equipment.
AUTOMATIC TORQUE BOOST (ITEM 2) - Automatically increases the percentage of
voltage boost when starting torque requirements are abnormally high.
TORQUE BOOST (ITEM 3) - Increases the voltage (voltage boost) to the motor for
increased starting torque.
BASE FREQUENCY OF MAXIMUM VOLTAGE LEVEL (ITEM 4) - Sets the base
operating frequency at which the output voltage is 100%.
STANDARD SETTING MODE SELECTION (ITEM 5) - This parameter automatically
enters the optimum settings for operating either a 50Hz or 60Hz motor or factory default
settings. A reset to factory settings can be made from this parameter.
ACCELERATION TIME #2 (ITEM 6) - Sets an alternate time required to accelerate
from OHz to the maximum frequency (FH). Use function [:SEL2] to select either
acceleration time #1 or #2. Setting this time to low can cause undue stress and
over current tripping of the drive.
DECELERATION TIME #2 (ITEM 7) - Sets the time required to decelerate from
maximum safe frequency (FH) to OHz. Use function [:SEL2] to select either deceleration
time #1 or #2. Setting this time to low can cause undue stress and over voltage
tripping of the drive.
PATTERN OF ACC/DEC #1 (ITEM 8) - Select one of three output frequency patterns.
These patterns are shown in the pattern curves below. Use function [:SEL2] to select
either acc/dec pattern #1 or #2.
Linear Pattern
The Linear pattern accelerates linearly.
The S-shaped pattern gradually accelerates a motor in a range where the motor provides
a low torque. This is particularly suited for material handling machinery.
S-shaped PatternC-shaped Pattern
The C-shaped pattern quickly accelerates a motor in a range where the motor provides
a low torque. This is well suited for a high speed run.

9.2 USER GROUP PARAMETERS (cont'd)
PATTERN OF ACC/DEC #2 (ITEM 9) - Select as an alternate one of the three output
frequency patterns. These patterns are the same as those for acc/dec pattern #1 and
are shown in the pattern curves from the previous page. Use function [:SEL2] to select
either acc/dec pattern #1 or #2.
SELECTION TO USE ACC/DEC #1 OR #2 (ITEM 10) - Use this function to select
either acc/dec #1 or acc/dec #2.
V/F PATTERN (ITEM 1 1)- Use this function to select either constant or variable torque.
The V/f characteristic may be set for constant torque loads, resulting in a linear
relationship between output voltage and frequency. The setting for variable torque loads
sometimes results in energy savings and lower motor noise, if the application is suitable.
Fans and centrifugal pumps are the most common types of loads associated with the
variable torque load V/f pattern.

9.3COMMUNICATION GROUP PARAMETERS
AUTOMATIC RESTART AFTER INSTANTANEOUS POWER FAILURE SELECTION
(ITEM 1) - Use this function to select auto-restart on or off. When selected, the inverter
will automatically restart into a free-rotating motor. This restart will occur only after an
instantaneous power interruption has occurred. The function allows the inverter to
sample the speed of the free-rotating motor at the end of the interruption and output a
matching frequency when power is reapplied. This assures smooth restarts of a freerunning motor when an instantaneous power loss has occurred such as when the
system is switched from a commercial bypass run to an inverter run.
AUTOMATIC RESET SELECTION (ITEM 2) - When this function is selected, the inverter
will automatically try to reset itself and restart the motor when a protective function
activates fault trip. The following chart shows the auto-reset procedure for over-current
and over-voltage fault trips.

Fault relay will be cleared after reset.
The reset process follows this chart
unless a fault, other than those listed,
occurs. If this happens the Inverter will
not try to reset.
TOSHIBA
If the inverter is able to reach the original operating speed where the trip occurred, while
trying to restart, then the reset process counter resets to zero. The process now begins
again from 1st restart even if the original overcurrent condition still exists. While
preparing for a reset, the auto-reset function causes the fault code "0.0" to be displayed
alternately on the monitor display. Fault detection signals are not output during the
reset process. If the cause of the failure has not been corrected, then the intervals
before each attempted reset will be prolonged (See above chart). If the load exhibits
an extremely large amount of inertia, automatic restart using the above procedure
may not work.
No restart is tried when any of the following messages are displayed:
"OCA" Overcurrent (transistor short-circuit at start-up)
"OCL"
"EF"

9.3 COMMUNICATION GROUP PARAMETERS (cont'd)
POWER FAILURE FUNCTION SELECTION (ITEM 3) - When this function is selected,
the inverter will use the regenerative energy of a running motor to extend the power off
ride through capability during momentary power dropouts (approximately 100mS). There
are some cases when continuous operation is not possible due to the machines's inertia
or load status, so this feature should be used in combination with the retry function.
This function is valid oniy on the 230 voit units.
FAULT TRIP DATA RETENTION SELECTION (ITEM 4) - This function can be set to
store trip data in the EEPROM. The trip status data stored in this manner is available for
observation while occurring or anytime after the drive has tripped. If the trip data is stored
in this manner then the drive can only be started by manually resetting the drive [:typ]=3.
See Tripped Status Monitoring Page 8-3.
INPUT TERMINAL SELECTION (ITEM 5) - Use this parameter to configure the inverter
to recognize functional combinations of terminal inputs SS2, SS3, JOG, and AD2. See
Input Terminal Operation Chart on page 10-1. This chart shows all of the combinations
and the way that operating frequency can be selected by shorts or opens across these
terminal inputs.
OUTPUT TERMINAL SELECTION (ITEM 6) - Use this parameter to configure the
inverter for output functional combinations of terminals LL, UL, LOW, and RCH. See
Output Terminal Operation Chart on page 10-1. This chart shows output configurations
that can be assigned to these terminals.

to assign the inverter. This will electronically "tag" the inverter when operating on a serial
bus with other inverters. This is used oniy when the "Muiti-Functional Option Board"
is instalied.
BAUD RATE (ITEM 9) - Use this function to select the serial communication bit transfer
rate. This is used only when the "Multi-Functional Option Board" is installed.
COMMUNICATION DATA BITS (ITEM 10) - Use this function to select the serial
communication bit word length in the communication protocol. This is used only when
the "Multi-Functional Option Board" is installed.
COMMUNICATION PARITY CHECK AND STOP BIT (ITEM 11) - Use this function to
select the serial communication protocol. This is used only when the "Multi-
Functional Option Board" is installed.
PWM CARRIER FREQUENCY (ITEM 12) - Use this function to select the pulse width
modulated carrier frequency. The acoustic noise of the motor changes when the PWM
carrier frequency is changed. Changing the carrier frequency is usually effective in
quieting the mechanical vibration noise caused when a resonance occurs at the load
machine fan cover. Other system characteristics are also affected by the carrier
frequency. Higher carrier frequencies cause additional heating of the inverter because of
faster transistor switching speeds. Overheating of the inverter may become a
problem at higher carrier frequencies and extremely heavy loads. Consult factory
before changing.

JUMP FREQUENCY GROUP PARAMETERS
JUMP FREQUENCY #1 (ITEM 1) - Use this function to set the beginning point of a
frequency bandwidth to be skipped when running a motor. This function is to be used in
conjunction with the bandwidth which is set by Jump Width #1. This function is to be
used when a certain frequency is to be avoided, such as the resonance frequency of a
loaded machine. Frequency jump does not engage when either accelerating or
decelerating through the programmed frequencies and bandwidths. It does prevent a
frequency setting from running continuously in one of the bandwidths assigned to be
locked out by this procedure.
JUMP WIDTH #1 (ITEM 2) - Use this function to set the bandwidth for Jump
Frequency #1.
JUMP FREQUENCY #2 (ITEM 3) - Use this function to set the beginning point of a

should be used when a second resonant frequency should be avoided.
JUMP WIDTH #2 (ITEM 4) - Use this function to set the bandwidth for Jump
Frequency #2.
JUMP FREQUENCY #3 (ITEM 5) - Use this function to set the beginning point of a
third frequency bandwidth to be skipped when running a motor. This function is to be
used in conjunction with the bandwidth which is set by Jump Width #3. This function
should be used when a third resonant frequency should be avoided.
JUMP WIDTH #3 (ITEM 6) - Use this function to set the bandwidth for Jump
Frequency #3.
PIP SETPOINT CONTROL SELECT (ITEM 7) - Use this function to select proportional,
integral, or differential gain (PIP) either "on" or "off". This function is to be used in
conjunction with the following functions of Proportional Gain, Pifferential Gain, and
Integral Gain.

be displayed. Use this function as a multiplication or division (fractional multiplication)
scaler to convert to other units.
LOW SPEED DETECTION (ITEM 2) - Use this function to setup a low speed signal
output. This function allows the drive to signal when the output frequency is greater than
or equal to the selected "low speed frequency". The LOW(LL) terminal (see control/
driver terminal block details on page 5-5) is normally the high impedance state of an
open collector transistor. This terminal will go low (ground) when the low speed detection
frequency is reached.
SPEED REACH SELECTION (ITEM 3) - Selects the option to output a signal when an
acc/dec is complete or when the output frequency is within a selected range. The
RCH(UL) terminal (see control/driver terminal block details on page 5-5) is normally the
high impedance state of an open collector transistor. This terminal will go low (ground)
when the speed reach detection frequency is reached. If a frequency range is selected
then "Speed Reach Detection Range" and "Speed Reach Reference" functions
should also be set.
SPEED REACH DETECTION RANGE (ITEM 4) - Use this function to specify a range of
frequencies, above and below the speed reach reference frequency. When the output
frequency is within this range terminal RCH(UL) will be "on". See functions "Speed
Reach Selection" and "Speed Reach Reference".

detection frequency in the center of the speed reach detection range. See functions
"Speed Reach Selection" and "Speed Reach Detection Range".

the frequency at which DC injection voltage will begin to be applied to a motor during a
decelerating stop. This function is used for precise positioning (inching) of the motor
driven equipment. Use this function in conjunction with functions "DC Injection Voltage"
and "DC Injection Time".
DC INJECTION VOLTAGE (ITEM 7) - Use this function to specify the percentage of total
DC injection to apply during the injection time. Use this function in conjunction with
functions "DC Injection Voltage Start Frequency" and "DC Injection Time".
DC INJECTION TIME (ITEM 8) - Use this function to specify the length of time that the
DC injection voltage is to be applied. Use this function in conjunction with functions "DC
Injection Voltage" and "DC Injection Voltage Start Frequency".
OUTPUT VOLTAGE REGULATION (ITEM 9) - This function allows the V/f
characteristics to be set for a motor with a lower rated voltage by setting the V/f
characteristics for 100% output voltage and then proportionally reducing the output
voltage to the required level. An output voltage greater than the input voltage is not
possible but the output voltage can be reduced proportionally to the input voltage.
OVERVOLTAGE STALL PROTECTION SELECT (ITEM 10) - Use this function to select
an automatic lengthening of the deceleration time. Large inertia loads and/or rapid
deceieration can create motor regeneration overvoitage on the DC bus. This
condition can cause a trip and use of this function should be considered.

10.0 Input Terminal Operating Functions
Terminal operations are described as those operational features that can be controlled by
opening or closing relays (switches) across the terminal block (see Control/Driver Board Terminal
Block Details page 5-5). All of the functional combinations which can be accessed by terminal
control are discussed in this section. Remote operations from the terminals are possible even if
the inverter is in the manual control mode, however many of the terminals are multi-functional
(used for more than one function) and must be programmed for a particular application. Also
some of the terminals can be program disabled. Many of the operations that can be performed
by this inverter require program configuration and use of the terminals. Some of these functions
include Jog, Remote preset speeds. Remote meters. Outputting limit signals, and remote
start/stop.

input signal is applied.
ONOFFONThe inverter is ON and will run in a REVERSE direction if an
input signal is applied.
ONONONSame as REVERSE connection above.
ON = dry contact closure, OFF = dry contact opening
Notes:
1) With ST-CC (ON), switching F-CC or R-CC (OFF) will cause the motor to decelerate to a stop.
2) If input power is turned off (with MCCB) while inverter is running, the motor will coast to a stop.
Avoid using the input power switch to start and stop the motor use for an emergency
stop oniy.
3) Acceleration and Deceleration rates are determined by the preset values of function [:ACC1],
[:ACC2] and [:DEC1], [:DEC2].
4) When switching from a forward run to a reverse run the motor will decelerate to a stop then
accelerate in the reverse direction.
10.3 Emergency Stop From a Remote Location
A SPST normally closed latch-in type of switch should be connected between ST-CC.
This switch can then be located in a remote location. When the switch is "toggled" to
latch open, the motor will coast to a stop.
Do not toggie this switch ON again untii the inverter is turned OFF (the
CAUTION
output frequency reads zero) and the motor ioad has stopped rotating.
10.4 Remote control Frequency Setting
The drive can be run at various frequencies by use of external analog voltage and current
control signals applied to terminals IV and RR. The keypad is not used for this operation
other than assignment of values and programming instructions. It may be desirable from
a security standpoint to disable the touchpad, when programming is completed, so that
customer parameters and programming cannot be changed or revised. Use function
[:RR.cc] item 2 on page 7-5 to set the terminals. When the IV input is selected, an
auto-mode is in effect so that voltage sensing terminal RR will override current
sensing terminal IV if a voltage is applied to terminal RR. See Terminal/Jumper
Connections for Input Reference Signals chart on page 5-6.

10.5 Jog
The jogging frequency is immediately output when the remote JOG is activated. The
functions [JOG] and [J.StP] must be preset. In addition, the JOG(SS2) terminal must
be set for "JOG". This is accomplished by setting the function parameter [:l.tb] to 1 or 3.
The terminal connections are shown below:

Notes:
1) A jogging run cannot be engaged by closing the JOG switch during a run.
2) The inverter will decelerate at the selected rate during: deceleration stop, coast to stop, and DC
injection stop.
3) F-CC must be broken for DC injection to be applied; breaking only JOG(SS2)-CC allows the
inverter to accept other input signals and is not a "true" off.
4) See table on next page for terminal inputs and actions.
10.6 Resetting After a Trip
Pressing reset on the keypad resets the inverter faults. Momentarily closing a normally
open dry contact between terminals RST and COM resets the inverter faults remotely.
When the inverter trips due to an emergency stop or the activation of
one or more of its protective functions, the cause of the fauit must be
CAUTION corrected before resetting the inverter. A forced restart with out prior
fauit correction measures couid damage the inverter and connected
devices.

10.7 Pattern Run
(Pt.1)
The pattern run enables the user to run up to seven different speeds automatically, in
either forward or reverse directions. It is an extension of the seven preset speeds
described on page 9-9. Unlike the Preset Speed Function, the user can pre-select the
length of time in which the inverter will operate at each frequency (Sri -Sr7), as well as
the acceleration/deceleration pattern used to reach each frequency.
The required preset function parameters are as follows:
1) Actual run frequencies (Sri[:S.PrG] Item 2 through 8.
2) The run time for each of these frequencies in the pattern (Pt.1t~Pt.7t) is
located in Pattern Frequency Group Parameters [:P.PrG] Item 6, 8, 10,
12, 14, 16, and 18.
3) The particular ACC/DEC drive characteristics, including the run direction, to be
used is located in Pattern Frequency Group Parameters [:P.PrG] Item 7, 9, 11,

•Sr7) are located in Speed Group Parameter
The run time set for each pattern includes the ACC/DEC time required to reach that
particular run frequency. Therefore, care must be taken when choosing run times. For
example, if the pattern run time is set for 30 seconds and the acceleration time required
to reach the preset frequency is 20 seconds, then the actual run frequency would last
only 10 seconds.

10.8 PID Set Point Control
All Q-Flowsaver II inverters come standard with set point control. The following
information shows how to install and adjust the inverter using set point control. The
feedback signal should be either 0-5 volts or a 4-20mA current. It is connected to
terminals IV and CC. The set point is adjusted by using a potentiometer. The diagram
below shows how a potentiometer should be connected to terminals PP, RR, and CC
to control the setpoint. Each of these connections are made to the Control/Driver
Board terminal block (see detail Page 5-5). The connection diagram below shows
the necessary wiring.
TOSHIBA
Use the following procedures to adjust the setpoint control parameters:
INITIAL SETUP
1) Remove power and place the jumper connections JP1 and JP2 (See detail 1 or 2
Page 5-5 and Jumper/Terminal Connections and Functions Page 5-6) in the correct
positions for the type of feedback signal used; power can then be applied again.
2) Set acceleration and deceleration times to 5 seconds (see Setup Parameters
Item # 1 and 2).
3) Adjust the bias and gain for the systems feedback signal. For example, typically the
motor slows down when the feedback signal goes above the setpoint. This action
can be reversed by exchanging the data between F-P1 and F-P2 (see Setup
Parameters Item # 6 and 8).
4) Turn on the set point (PID) control (see Jump Frequency Group parameters Item #7).
5) Set proportional gain to 250 (see Jump Frequency Group parameters Item #8).
6) Set integral gain to 100 (see Jump Frequency Group parameters Item #9).
7) Set differential gain to 0 (see Jump Frequency Group parameters Item #10).
8) Set lag-time constant to 255 (see Jump Frequency Group parameters Item #11).
9) Run system.

11.0 Output Terminal Operating Functions
The inverter provides terminals for outputting signals to external components. A number of
selectable "operating" output signals, as well as "fault" output signals, are available. These output
signal terminals are located on the terminal board (See Control/Driver Terminal Block Details on
page 5-5).
11.1 Selectable Outputs
The output terminals RCH(UL) and LOW(LL) are multifunctional and are selectable through
function [:0.tb] (See item 6 on page 7-3). The type of selections are available as shown below:
LL Outputs a signal when frequency is greater than or equal to the LL value.
UL Outputs a signal when frequency is equal to UL value.
LOW Outputs a signal when frequency is greater than or equal to the LOW SPEED
DETECTION VALUE "LF".
RCH Outputs a signal based upon the selection of the RCH parameters rCH, rrCH, FrCH.
All output signals are open-collector with 50mAdc~24Vdc ratings.
The illustrations below show output timing diagrams for the upper and lower frequency limits
and for low speed and speed reach signals.

Upper/lower limit frequency signal output
Low speed/speed reach signal output with rCH=1

11.2 Inverter to Relay/PC Connections
Terminals RCH (UL) and LOW (LL) of the control circuit terminal block are open collector
outputs which float in an open state. When the predesignated frequency has been
reached the terminals can sink 24Vdc at SOmAdc to ground. P24 supplies 24Vdc through
the relay colls to the RCH (UL) and LOW (LL) terminals for relay activation. Connections
are shown below for either relay logic or programmable controller Inputs. Notice that
there is no difference in the circuits except how the relay outputs are utilized.

not conduct during normal current flow.
(Consult factory for specific applications)
Note:
When an output frequency fluctuates in the vicinity of a frequency to be reached, the reach signal
may alternately turn on and off because of the lack of hysteresis in the reach signal.
11.3 Fault-Detection Output Terminals
When any of the inverter's system protection features are activated and the inverter trips
(See list of probable causes on Page 8-3), the cause of the problem will be displayed
and a fault-detection relay will be activated. This will cause the contacts associated with
the Fault-Detection Output Terminals to change state. Three fault detection terminals

11.4 Calibration of Remote Meters
Many times an application requires that a frequency meter (FM) or ammeter (AM) be
remotely located. Attachment and calibration of a remote meter is a easy procedure.
The meter leads should be connected to the appropriate terminals while observing
correct polarity. The calibration of the meter is performed with the inverter keypad while
observing the meter. The meter should be zeroed with the set screw before calibrating.
If the meter is not visible from the inverter site, then the meter should be viewed
periodically as the keypad is adjusted. Also the meter can be connected through a
temporary length of cable for easy viewing. This temporary cable should be the same
size and length as the permanent cable.
Use the following diagram for connecting a Frequency Meter (FM):

Although the above procedure shows calibration of the remote meter at a running
frequency of 60Hz; better resolution of the meter can be obtained if the inverter is
running at the maximum frequency. The motor load should be disconnected for
FM calibration at the highest frequency.
