VS-616PS5 Programming Manual3
READ THIS ENTIRE MANUAL BEFORE INSTALLING OR OPERATING THE VS-616PS5!
WARNING!
The PS5 motor uses permanent magnets. HIGH VOLTAGE is generated by the
motor whenever the rotor is turning, with or without a power supply. Make sure
the motor is not turning before performing ANY service on the motor or on the
inverter.
If there is a possibility that the motor can be turned by the load while inverter
power is off, install a contactor or a manual disconnect to open the motor leads
while servicing the inverter. Interlock the disconnect with the control circuits of
the drive.
ONLY PERSONNEL WHO ARE EXPERIENCED IN WORKING WITH HIGH VOLTAGE, HIGH
POWER EQUIPMENT SHOULD INSTALL OR SERVICE THIS EQUIPMENT.
Turn off the supply power to the VS-616PS5 AND make sure the motor is stopped AND the internal
capacitors are discharged before connecting or disconnecting wires or touching any internal parts.
The VS-616PS5 internal capacitors remain charged even after the power supply is turned off. Wait
at least five minutes after removing power. Make sure all LED’s are off before servicing the inverter.
Do not use a Megger or other type of high withstand voltage tester on the VS-616PS5. Higher volt-
ages can damage the semiconductors used in the inverter.
Do not connect or disconnect the operator or a computer while the VS-616PS5 is running.
FAILURE TO OBSERVE THE WARNINGS AND PRECAUTIONS IN THIS MANUAL CAN EXPOSE THE USER TO HIGH
VOLTAGES, RESULTING IN DAMAGE TO EQUIPMENT, SERIOUS PERSONAL INJURY, OR EVEN DEATH.
POWER SUPPLY LIMITATIONS

B5 PID Control
B5PID Control
The Proportional, Integral, and Derivative (PID) control function provides closed-loop
control and regulation of a system variable such as temperature or pressure. A control signal based on the difference (or error) between a feedback signal and a desired
setpoint is produced. Integration and derivative calculations are then performed on
this signal, based upon the PID parameter settings (B5-01 to B5-08), to minimize
deviation, for precise control.
B5-01 PID Control Mode SelectionA
To enable PID control, set PID control mode selection to “1” or “2”, according to the
description below. Also be sure to set terminal 16 function selection (H3-05) to PID
feedback (Set Value: “B”).
SettingDescription
0PID is disabled (factory default).
1PID is enabled (deviation signal is put through derivative control).
2PID operates with feed forward (feedback signal is put through derivative control).
Notes:
1. PID with feed forward applies control much quicker than normal PID, without waiting for the
deviation signal to build up.
2. A PID inverse feedback signal can be selected by inverting the settings for terminal 16 gain
and bias.
Then select the PID control intended value (setpoint) and detected value (feedback)
setpoint as follows:
Detected Value (Feedback)
Set the PID feedback value with the control circuit terminal 16 voltage signal (0 to
10V, -10 to 10V) or multi-step speed parameters H1-03 to H1-06.
Control circuit terminal 16 voltage signal:
Set reference selection (B1-01) to “1” and set H3-05 = “B”.
Multi-step speed parameters via multifunction inputs (H1-01 to H1-06):
Set reference selection (B1-01) to “0.”
Set multifunction inputs to (H1-01 to H1-06) set value 3,4 and/or 5.
(allows combination of multi-step speed references and jog frequency reference
as entered in parameter D1-01 thru D1-09)
Intended Value (Setpoint)
The control circuit terminal 14 current signal (4 to 20mA) or voltage signals (0 to 10V,
-10 to +10V) can be used to set the PID setpoint value.
Control circuit terminal 14 accepts 4-20 MA current signal:
Set terminal 14 signal selection (H3-08) to “2.”
18VS-616PS5 Programming Manual
Section B: Application Parameters
B5 PID Control
Control circuit terminal 14 accepts voltage signal:
Set terminal 14 signal selection (H3-08) to “0” for 0-10 VDC input signal or “1” for 10 to 10 VDC input signal. The J1 jumper must also be cut to set-up terminal 14
to accept a voltage signal.

Figure 9 PID Control Block Diagram
Notes:
1.I value is reset to ”0” when operation stops.
2.The upper limit of the I value can be set by parameter B5-04.
Increase the value of parameter B5-04 to upgrade control capability by
integration. If the control system is unstable and it cannot be stopped by
adjusting the integral time, output delay time, etc., decrease the set value
of parameter B5-04.
3.PID control can be canceled by a multi-function contact input signal.
By setting any of parameters H1-01 to H1-06 to “19” and by closing the
contact during running PID control is disabled and the intended value signal itself is used as a frequency reference signal.
B5-02 PID Control Proportional GainA
Setting Range:0.00 to 25.00
Factory Default:1.00
The proportional gain is the value by which the deviation signal is multiplied to generate a new frequency reference. Too high a setting will result in oscillations (instability).
Too low a setting will result in a sluggish response.
VS-616PS5 Programming Manual19
Section B: Application Parameters
B5 PID Control
B5-03 PID Control Integral TimeA
Setting Range:0.00 to 360.0s
Factory Default:1.00s
The integral calculation sums the deviation over time which forces the deviation to
become zero. Thus, the feedback will match the desired setpoint. The integral time
determines how quickly the integral gain increase is added to the control loop. Too
high a setting will result in slow response. Too low a setting may result in rapid oscillations (instability).
B5-04 PID Control Integral LimitA
Setting Range:0.0 to 100.0%
Factory Default:100.0%
The integral limit is used to limit the range of the integral term. In some applications it
may be desirable to limit the integral term to improve system response. Otherwise,
the integral value may become large and overshoots may result when the integral
value takes a long time to integrate in the opposite direction. This value is set as a
percentage of maximum motor speed (E1-06).
B5-05 PID Control Derivative TimeA
Setting Range:0.00 to 10.00s
Factory Default:0.00s
The derivative calculation attempts to control the remaining overshoot left over after
the proportion and integral calculations. If the system is approaching the intended
value very rapidly, the derivative control produces a strong braking action to prevent
overshoot. If the system is already stable with very little deviation change, derivative
control has very little effect. The derivative time is used to dampen oscillations and
reduce overshoot, thus improving stability. Setting the derivative time to a larger
number produces more braking action in the control system.
B5-06 PID Control LimitA
Setting Range:0.0 to 100.0%
Factory Default:100.0%
The PID limit places a limit on the PID signal output, limiting the output frequency reference. Normally this is set to 100% to allow unrestrained operation of the PID function. This value is set as a percentage of maximum motor speed (E1-06).
20VS-616PS5 Programming Manual
Section B: Application Parameters
B5 PID Control
B5-07 PID Control OffsetA
Setting Range:±100.0%
Factory Default:0.0%
The PID offset adds a bias to the calculated PID value.
B5-08 PID Control Output Primary Delay TimeA
Setting Range:0.00 to 10.00s
Factory Default:0.00s
The output delay time builds in a delay to changes in the calculated PID value, which
can prevent oscillations and improve stability. Use the PID Delay Time when transients occur in the system and it is undesirable to have the PID respond.
Parameters B5-04 thru B5-08 are preset at the factory to optimum values for most
applications, and hence, do not need to be changed.
When tuning a system, first increase the proportional gain until oscillations occur.
Then, reduce the proportional gain slightly until the oscillations stop. Next, reduce the
integral time slowly until oscillations begin. Then, increase the integral time slowly so
that the oscillations cease. Test the system under all conditions, observe the stability
and verify that the desired operation is generated. Fine tune the proportional and integral times, along with any other PID parameter as needed.

B6 Reference Hold
B6Reference Hold
The reference hold or dwell function is used to temporarily hold the output frequency
at a set reference, for a set time, during the acceleration and deceleration process.
Use this function when driving a permanent magnet motor, or a motor with a heavy
starting load. The pause in acceleration allows the magnets in a permanent magnet
motor to synchronize with the stator field of the motor, thus reducing traditionally high
starting current.
B6-01 Dwell Reference at StartA

Figure 28 Speed/Torque Control Selection Timing Diagram
Sequence Description
• When the speed/torque control selection contact is OPEN, speed control is activated:
• Speed reference during speed control depends on the frequency reference
selection (B1-01) setting. To use terminal 13 or 14 as the master frequency reference, set Bl-0l to “l.”
• Torque limit during speed control is the smaller of the absolute value of terminal
16 torque limit (H3-05 = 13), or the values set in the torque limit parameters (L7-01 to L7-04).
• When a stop command is given during speed control, speed control is maintained and the smaller of the absolute value of terminal l6 torque limit, or the values set in the torque limit parameters (L7-01 to L7-04), is used as the torque
limit. Then the motor decelerates to stop.
‚ When the speed/torque control selection contact is CLOSED, torque control is
activated:
• Speed limit during torque control is:
• the master frequency reference at terminal 13 or 14 when speed limit selection
(D5-03) is set to “1”
• the speed limit value (D5-04) when D5-03 = “2,” regardless of the frequency reference selection (B1-01) setting.
• During torque control, the terminal 16 analog input value becomes the torque
reference.
ƒ By giving a stop command during torque control, operation changes to speed control automatically, and the motor decelerates to stop. The torque limit during deceleration to stop becomes the values set in the torque limit parameters (L7-01 to L7-04).
Note:The control mode actually changes after the speed/torque control selection command changes and
after the reference delay timer (D5-06) elapses. The terminal 13 speed reference/speed limit and the
terminal 16 torque limit/torque reference are stored in the inverter until the time set to D5-06 passes.

• Local/Remote Selection (setting: “1”)
Selects the operation mode, only when the inverter is stopped.
Local:Operation according to frequency reference and run command as
entered from digital operator.
Remote: Operation according to frequency reference and run command set by
B1-01 & B1-02, respectively.
Note: When local/remote selection is set by a multi-function contact input ter minal, local/remote selection from the digital operator key is disabled.
• Option/Inverter Selection (setting: “2”)
Selects whether operation is performed using a reference command from an option
card or from the inverter. Changeover is effective only when the inverter is stopped.
Open:Runs by frequency reference and run command from inverter control
circuit terminal or digital operator (B1-01 & B1-02 dependant).
Closed:Runs by frequency reference and run command from an option card.
• External Baseblock N.O. (setting: “8”)
Baseblock operation is performed when the contact input is closed. External baseblock operation differs, as described below, depending on the run command input
status.
Inputting an external baseblock signal while the inverter is running, causes a “BB”
indication on the digital operator display, and the inverter output is shut OFF.
After removing the external baseblock command, operation restarts at the previously referenced speed.
Inputting a stop signal along with an external baseblock signal while the inverter is
decelerating, causes” BB” to blink on the digital operator, the inverter output to shut
OFF, and the frequency reference to reset to 0.
• External Baseblock N.C. (setting: “9”)
Baseblock operation is performed similar to setting “8,” except that operation is performed when the contact input is open.
• Accel/Decel Hold Command (setting: “A”)
The accel/decel hold command is used to temporarily hold the output speed at its
current level at the time the “Hold” command is applied. Upon entry of a stop command, the accel/decel hold condition releases and operation stops.

Notes:
1. When both a hold reference memory selection (D4-01 = “1”) and an accel/
decel hold command are input, a stop command followed by a run command
will generate storage of the output frequency data until the accel/decel stop
command is released. Operation resumes after the frequency storage.
2. When the power supply is turned OFF after the accel/decel hold command is
input, the held output frequency is also stored.
3. When D4-01 is set to “0,” the held output frequency is not stored.
• Inverter Overheat OH2 Alarm (setting: “B”)
Inputting the inverter overheat alarm signal, “OH2” blinks on the digital operator display (Alarm condition only). The user can connect the dry contact of an external
heat sensor for indication of device over-temperature. To close an output contact
under this condition, set a multi-function contact output (H2-XX) to “20”.
• Multi-function Analog Input Enable/Disable (setting: “C”)
This setting allows terminal 16 multi-function analog input to be enabled (accepted)
or disabled (disregarded) via a digital input.
Open:Terminal 16 command is not accepted.
Closed:Terminal 16 command is accepted.
• Speed Control Integral Value Reset (setting: “E”)
This function allows the speed control integral value to be reset while the inverter is
running.
Open:PI-control (adds the speed control integral values.)
Closed:P-control (resets the speed control integral values by the integral time
constant).

L4 Reference Detection
L4Reference Detection
The VS-616PS5 utilizes three different functions for detecting output speed:
• When speed agree is enabled at the multi-function contact outputs (H2-__ = “2” or
“13”), the contact closes whenever the output speed “agrees” with the speed reference, plus or minus the speed agree detection width.
• When desired speed agree is enabled at the multi-function contact outputs (H2-__ =
“3” or “14”), the contact closes whenever the output speed “agrees” with the speed
agree detection level, plus or minus the speed agree detection width.
• When speed detection is enabled at the multi-function contact outputs (H2-__ = “4”,
“5”, “15” or “16”), the contact closes whenever the output speed is less than or more
than the speed agree detection level, depending on which detection is selected.
Refer to section H2, Digital Outputs, for more detailed information on setting these
functions.
L4-01 Speed Agree Detection Level (without sign)B

L5 Fault Reset
L5Fault Restart
After a fault occurs, the inverter can be reset automatically. The automatic restart
function allows the inverter to reset itself and continue operation after certain faults
(Provided the fault condition no longer exists.
L5-01 Number of Automatic Restart AttemptsB
Setting Range:0 to 10
Factory Default:0
Sets the number of automatic restart attempts. Setting to “0” disables this function.
Automatic Restart Operation
• When a fault is detected, the inverter output shuts OFF. The digital operator displays the fault while the inverter output is shut OFF.
• The fault is reset automatically and speed search starts from the motor speed as
detected by the PG feedback.
• When the total number of faults exceeds the number of automatic restart attempts,
the faults are not reset automatically and the inverter output remains OFF. At this
time, a fault contact output is activated.
The inverter can be set to automatically restart after the following faults occur:
• Overcurrent (OC)
• Overvoltage (OV)
• Undervoltage PUV (UV1)
• Ground fault (GF)
• Regenerative transistor fault (rr)
Automatic restart is not available for the following faults:
• Control circuit undervoltage (UV2) • Excessive speed deviation (DEV)
• MC answer-back fault (UV3)• PG disconnection (PGO)
• Heatsink overheat (OH)• Communication error (CE)
• Run command fault (EF)• External fault (EF3 to EF8)
• Overspeed (OS)
The number of restart attempts is reset to 0 when:
• A fault does not occur for more than 10 minutes after the last restart has been performed.
• A fault reset command is input from the control circuit terminal or the digital operator.
• Power is cycled.
