How to Use the Password
The user can set a password in parameter A1-05 to restrict access to the drive. The password must be entered to A1-04 to
unlock parameter access (i.e., parameter setting A1-04 must match the value programmed into A1-05). The following
parameters cannot be viewed or edited until the value entered to A1-04 correctly matches the value set to A1-05: A1-01, A1-02,
A1-03, A1-06, and A2-01 through A2-33.
The instructions below demonstrate how to set password “1234”. An explanation follows on how to enter that password to
unlock the parameters.

b3: Speed Search
The Speed Search function allows the drive to detect the speed of a rotating motor shaft that is driven by external forces and
start the motor operation directly from the detected speed without first stopping the machine.
Example: When a momentary loss of power occurs, the drive output shuts off and the motor coasts. When power returns, the
drive can find the speed of the coasting motor and restart it directly.
Enabling Speed Search for PM motors only requires setting parameter b3-01 to 1. The drive offers current detection and speed
estimation Speed Search for induction motors. Parameter b3-24 selects the speed search method for induction motors. Both
methods and relevant parameters are explained below.
Speed Search start timing differs depending on whether operation is after a momentary power loss (L2-01 = 1 or 2) or after
the Speed Search at start (b3-01 = 1). The operation timing of the Speed Search after a momentary power loss is shown in
Figure 1.9. The operation timing after the Speed Search at start is shown in Figure 1.10.
After restoring power, the Speed Search operation remains in baseblock status for at least the time set in b3-05. However,
Speed Search will not start if the time set in L2-03, Minimum Baseblock Time, does not pass after the power stops. When
induced voltage remains in the motor, the Speed Search operation starts after the time set in b3-05 without waiting for the time
set in L2-03.
When performing a speed search operation at start, the speed search operation will start after waiting for the longer of the
times set
Search operation starts after the time set in b3-05 without waiting for the time set in L2-03.

then accelerates or decelerates to the frequency reference after completing Speed Search.
This method can be used for a single induction motor connected to a drive. Do not use this method if the motor is one or more
frame size smaller than the drive, at motor speeds above 200 Hz, or when using a single drive to operate more than one motor.
Speed Search Activation
n
Speed Search can be activated using any of the methods 1 through 5 described below. Select the Speed Search type in parameter
b3-24 independent of the activation method.
Method 1. Automatically activate Speed Search with every Run command. Set b3-01, Speed Search Selection at Start, to 1
(Enabled). External Speed Search commands are ignored.
Method 2. Activate Speed Search using the digital input terminals.
Use the input functions for H1-oo in Table 1.7.

Activate Speed Estimation
Speed Search
Closed: Activate Current Detection Speed Search from the
maximum output frequency (E1-04).
Closed: Activate Current Detection Speed Search from the
frequency reference.
To activate Speed Search by a digital input, the input must be set together with the Run command or the Run command must
be entered after giving the Speed Search command.
Method 3. After automatic fault restart.
When the number of maximum fault restarts in parameter L5-01 is set higher than 0, the drive will automatically perform
Speed Search as specified by b3-24 following a fault.
Method 4. After momentary power loss.
This mode
requires that the Power Loss Ride-Thru function is enabled during CPU operation (L2-01 = 1 or 2). Refer to L2-01:
Momentary Power Loss Operation Selection on page 109.
Method 5. After external baseblock is released.
The drive will resume the operation starting with Speed Search if the Run command is present and the output frequency is
above the minimum frequency when the Baseblock command (H1-oo = 8 or 9) is released.
Rotation Direction Detection Conditions for Backspin
n
Backspin occurs when the motor rotates in the opposite direction from the rotation direction command. Specify the speed
search direction when power is recovered after a momentary power loss in applications in which backspin can occur, such as
for an oil pump when backspin may occur due to the weight of the oil after a momentary power loss. The search starts from
the rotation direction specified in the direction command when the momentary power loss time is short. The search starts from
the opposite direction of the direction specified in the direction command when the momentary power loss time is long. The
rotation for the Speed Search is determined as follows:
[t] is the time from the momentary power loss to recovery.
• 0 ≤ t < b3-50: The search is started in the direction specified by the direction command.
• b3-50 ≥ t < b3-51: The motor is not restarted and the baseblock continues.
The search starts from the opposite direction of the direction command when the momentary power loss time exceeds the
setting value of b3-51.
• b3-51 ≤ t: The search is started in the direction opposite to the direction command.
Refer to b3-50/b3-51: Backspin Search Direction Judgment Time 1/2 on page 28 for details on the backspin direction
judgment time.
Note: 1. Set b3-50 to the required time to enable rotation direction detection for backspin.
2. When setting b3-50, be sure to also set the following parameters to the values specified. Setting these parameters to any other values
will trigger an oPE08 fault.
b3-50 ≤ b3-51
b3-14 = 0
b3-24 = 2
3. Backspin detection is not necessary with a PM motor.

of system variables such as pressure or temperature.
P Control
n
The output of P control is the product of the deviation and the P gain so that it follows the deviation directly and linearly. With
P control, only an offset between the target and feedback remains.
I Control
n
The output of I control is the integral of the deviation. It minimizes the offset between target and feedback value that typically
remains when pure P control is used. The integral time (I time) constant determines how fast the offset is eliminated.
D Control
n
D control predicts the deviation signal by multiplying its derivative (slope of the deviation) with a time constant, then adds
this value to the PID input. This way the D portion of a PID controller provides a braking action to the controller response and
can reduce the tendency to oscillate and overshoot.
D control tends to amplify noise on the deviation signal, which can result in control instability. Only use D control when
absolutely necessary.

PID Feedback Loss Detection
n
The
PID feedback loss detection function detects broken sensors or broken sensor wiring. It should be used when PID control
is enabled to prevent critical machine conditions (e.g., acceleration to max. frequency) caused by a feedback loss.
Feedback loss can be detected in two ways:
• Feedback Low Detection
Detected when the feedback falls below a certain level for longer than the specified time. This function is set up using
parameters b5-12 to b5-14.
• Feedback High Detection
Detected when the feedback rises above a certain level for longer than the specified time. This function is set up using
parameters b5-12, b5-36, and b5-37.
The following figure illustrates the working principle of feedback loss detection when the feedback signal is too low. Feedback
high detection works in the same way.

Multi-function digital
outputs set for “PID feedback low” (H2-oo = 3E) will be triggered if the PID feedback value is below
the detection level set to b5-13 for the time set to b5-14 or longer. Multi-function digital outputs set for “PID feedback high”
(H2-oo = 3F) will be triggered if the PID feedback value is beyond the detection level set to b5-36 for longer than the time
set to b5-37. Neither a fault nor an alarm is displayed on the digital operator and the drive will continue operation. The multifunction digital outputs reset when the feedback value leaves the loss detection range.
Setting 1: Feedback Loss Alarm
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FBL - Feedback Low”
alarm will be displayed and a digital output set for “PID feedback low” (H2-oo = 3E) will be triggered. If the PID feedback
value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FBH - Feedback High” alarm will be displayed
and a digital output set for “PID feedback high” (H2-oo = 3F) will be triggered. Both events trigger an alarm output
(H2-oo = 10). The drive will continue operation. The alarm and multi-function digital outputs reset when the feedback value
leaves the loss detection range.
Setting 2: Feedback Loss Fault
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FbL - Feedback Low”
fault will be displayed. If the PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FbH
- Feedback High” fault will be displayed. Both events trigger a fault output (H2-oo = E) and cause the drive to stop the
motor.
Setting 3: Digital Output Only, even if PID Is Disabled by Digital Input
Same as b5-12 = 0. Detection remains active when PID is disabled by a digital input (H1-oo = 19).

Switching Accel/Decel Times by a Frequency Level
The drive can switch between different acceleration and deceleration times automatically. The drive will switch from accel/
decel time 2 in C1-03 and C1-04 to the default accel/decel time in C1-01 and C1-02 when the output frequency exceeds the
frequency level set in parameter C1-11. When the frequency falls below this level, the accel/decel times are switched back.
Figure 1.20 shows an operation example.
Note: Acceleration
For example, if accel/decel time 2 is selected, the drive will use only accel/decel time 2; it will not switch from accel/decel time 2 to the
selected time.
and
deceleration times selected by digital inputs have priority over the automatic switching by the frequency level set to C1-11.

Setting A: Accel/Decel Ramp Hold
When the
digital input programmed for the Accel/decel ramp hold function closes, the drive locks (holds) the output frequency.
Acceleration or deceleration resumes when the input is reopened.
If the Accel/decel ramp hold function is enabled (d4-01 = 1), the drive saves the output frequency to memory when the Ramp
Hold input is closed. When the drive is restarted after stop or after power supply interruption, the saved output frequency
becomes the frequency reference (provided that the Accel/decel ramp hold input is still closed). Refer to d4-01: Frequency
Reference Hold Function Selection on page 55 for details.
Setting B: Drive Overheat Alarm (oH2)
Triggers an oH2 alarm when the contact closes. Drive operation is not affected because this is an alarm.
Setting C: Analog Terminal Input Selection (Terminals A1 and A2)
When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analog
terminals.
Setting F: Through Mode
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in
the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or APOGEE
FLN, BACnet, MEMOBUS/Modbus, or Metasys N2 communications.
Settings 10 and 11: Up/Down Function
The Up/Down function allows the frequency reference to be set by two push buttons when one digital input is programmed
as the Up input (H1-oo= 10) to increase the frequency reference and the other digital input is programmed as the Down input
(H1-oo= 11) to decrease the frequency reference.
The Up/Down function takes priority over the frequency references from the HOA keypad and the analog inputs (b1-01 = 0,
1). When using the Up/Down function, references provided by these sources will be disregarded.
The inputs operate as shown in the table below:

hold function. Refer to the Troubleshooting chapter in the User Manual packaged with the drive for more information
Drive Operation
Using the Up/Down Function with Frequency Reference Hold (d4-01)
• If the frequency reference hold function is disabled (d4-01 = 0), the Up/Down frequency reference will be reset to 0 when
the Run command is cleared or the power is cycled.
• When d4-01 = 1, the drive will save the frequency reference set by the Up/Down function. When the Run command or the
power is cycled, the drive will restart with the saved reference value. Close the Up or Down input without an active Run
command to reset the saved value. Refer to d4-01: Frequency Reference Hold Function Selection on page 55.
Using the Up/Down Function with Frequency Reference Limits
Parameter d2-01 determines the upper frequency reference limit.
The value for the lower frequency reference limit depends on the parameter d4-10 setting. This value can be set by an analog
input or parameter d2-02. When a Run command is applied, the lower limits function as follows:
• If the lower limit is set by d2-02 only, the drive accelerates to this limit as soon as a Run command is entered.
• If the lower limit is determined by an analog input only, the drive accelerates to the limit when both the Run command and
an Up or Down command are active. The drive will not start running if only the Run command is active.
• If the lower limit is set by both an analog input and d2-02, and the analog limit is higher than the d2-02 value, the drive
accelerates to the d2-02 value when a Run command is input. When the d2-02 value is reached, the drive accelerates to the
analog limit only if an Up or Down command is set.
Figure 1.34 shows an Up/Down function example with a lower frequency reference limit set by d2-02, and the frequency
reference hold function both enabled and disabled.
Settings 12 and 13: Forward Jog, Reverse Jog
Digital inputs programmed as Forward Jog (H1-oo = 12) and Reverse Jog (H1-oo = 13) will be Jog inputs that do not
require a Run command. Closing the terminal set for Forward Jog input will cause the drive to ramp to the Jog frequency
reference (d1-17) in the forward direction. The Reverse Jog will cause the same action in the reverse direction. The Forward
Jog and Reverse Jog command can be set independently.
Note: The Forward

Setting 14: Fault Reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run
command, clear the fault either by pressing the RESET key on the HOA keypad or closing a digital input configured as a Fault
Reset (H1-oo = 14).
Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.
Settings 15 and 17: Fast Stop (N.O., N.C.)
The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while the
drive is running, the drive decelerates to a stop in the deceleration time set to C1-09 (Refer to C1-09: Fast Stop Time on page
47). The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast Stop input, and switching
off the Run command.
•
To trigger the Fast Stop function with an N.O. switch, set H1-oo = 15.
•
To trigger the Fast Stop function with an N.C. switch, set H1-oo = 17.

Setting 30: PID Integral Reset
Configuring one of the digital inputs for PID integral reset (H1-oo
= 30) resets the value of the integral component in PID
control to 0 when the terminal is closed. Refer to PID Block Diagram on page 34 for more details.
Setting 31: PID Integral Hold
Configuring a digital input for Integral Hold (H1-oo = 31) locks the value of the integral component of the PID control as
long as the input is active. The PID controller resumes integral operation from the hold value as soon as the integral hold input
is released. Refer to PID Block Diagram on page 34 for more information on this function.
Setting 34: PID Soft Starter Cancel

not in 3-Wire Control, an oPE03 fault will occur.
The Jog 2 input causes the drive to ramp to the Jog Frequency Reference (d1-17) in the direction dictated by the Fwd/Rev
input of the 3-Wire Control mode. Acceleration to and from the Jog Frequency Reference is determined by the active Accel/
Decel parameters.

1.7 H: Terminal Functions
Setting 6A: Drive Enable
A digital input configured as a “Drive enable” (H1-oo = 6A) will prevent the drive from executing a Run command until
the input is closed. When the input is open, the HOA keypad will display “dnE” to indicate that the drive is disabled.
If a Run command is enabled before the terminal set for “Drive enable” closes, then the drive will not run until the Run
command is cycled (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will stop
according to the stop method set to b1-03 (Refer to b1-03: Stopping Method Selection on page 18).

Setting 70: Drive Enable2
A digital input configured as a Drive Enable2 input (H1-oo = 70) prevents the drive from executing a Run command until
the Drive Enable2 input is closed. When the Drive Enable2 input is open and a Run command is closed, the digital operator
will display “dnE”.
The Run command does not need to be cycled after the Drive Enable2 input is closed. The drive will run when both the Run
and
Enable2 inputs are closed. If the Drive Enable2 input is opened while the drive is running, the drive will stop using

H3: Multi-Function Analog Inputs
The drive is equipped with multi-function analog input terminals A1, A2, and A3. Refer to Multi-Function Analog Input
Terminal Settings on page 101 for a listing of the functions that can be set to these terminals.
H3-01: Terminal A1 Signal Level Selection
n
Selects the input signal level for analog input A1. Set jumper S1 on the terminal board accordingly for voltage input or current
input.
No. Name Setting Range Default
H3-01 Terminal A1 Signal Level Selection 0 to 3 0
Setting 0: 0 to 10 V with Zero Limit
The input level is 0 to 10 Vdc with zero limit. The minimum input level is limited to 0%, so that a negative input signal due
to gain and bias settings will be read as 0%.
Setting 1: 0 to 10 V without Zero Limit
The input level is 0 to 10 Vdc without zero limit. If the resulting voltage is negative after being adjusted by gain and bias
settings, then the motor will rotate in reverse.
Setting 2: 4 to 20 mA Current Input
The input level is 4 to 20 mA. Negative input values by negative bias or gain settings are limited to 0%.
Setting 3: 0 to 20 mA Current Input
The input level is 0 to 20 mA. Negative input values by negative bias or gain settings are limited to 0%.

Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc (20 mA) input at terminal A1 (gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V (4 mA, 0 mA) input at terminal A1 (bias).
Use both parameters to adjust the characteristics of the analog input signal to terminal A1.
Setting Examples
• Gain H3-03 = 200%, bias H3-04 = 0, terminal A1 as frequency reference input (H3-02 = 0):

A 10 Vdc input is equivalent to a 200% frequency reference and 5 Vdc is equivalent to a 100% frequency reference. Since
the drive output is limited by the maximum frequency parameter (E1-04), the frequency reference will be equal to E1-04
above 5 Vdc.
