Yaskawa VS-616PC5/P5 frequency converter practical application

SC: Public end

Analog input:

FS:+15 V power supply (20 mA max)

FV: Frequency Command Voltage (0~10 V, 20 k Ω)

FI: Frequency command current (4~20 mA, 250 Ω)

FC: Simulate Public End

Output signal:

M1, M2: Multi functional optocoupler output (such as in operation, consistent frequency, etc.)

MA, MB, MC: Fault relay contacts (MA-MC normally open, MB-MC normally closed, 250 VAC/1A or 30 VDC/1A)

AM, AC: Analog output (0~10 V, can be set as frequency, current, power, or DC bus voltage)

2.4 Anti interference measures

Control lines and power lines should be routed separately, with a minimum distance of 10 cm between them.

To simulate the given signal (FV/FI), shielded twisted pair cables must be used, with the shielding layer grounded at the single end of the frequency converter side.

Relays and contactor coils need to be connected in parallel with surge absorbers (such as MARCON series).

When the frequency converter is connected in parallel with a large capacity transformer (above 600 kVA) or switched into phase capacitors, a DC reactor (connected to ⊕ 1 and ⊕ 2) or an AC input reactor needs to be installed.

Chapter 3: Trial Operation and Basic Operations - Quick Get Started

3.1 Pre power on inspection

Confirm that the wiring is correct, especially if the power supply is not connected to the output terminal; Remove internal wire ends; Screw locking; The motor can rotate freely (it is recommended to disconnect the load).

3.2 Power on display and operation mode

After the power is turned on, the digital operator displays the frequency reference value (factory default is REMOTE mode). In REMOTE mode, the running command and frequency reference come from the control terminal; The LOCAL mode is controlled by the operator. Press the LOCAL/REMOTE key to switch modes while in shutdown mode. The SEQ and REF LEDs on the operator indicate the current reference source:

SEQ=TRM: Run command from terminal

REF=TRM: The frequency reference comes from FV/FI

SEQ=OPR: Run command from operator

REF=OPR: The frequency reference comes from the operator

3.3 Basic operating steps

Run through the operator:

Press the LOCAL/REMOTE key to enter LOCAL mode (SEQ/REF LED off).

Press the up and down keys to set the frequency reference.

Press the RUN key to start, press the STOP key to stop.

Running through terminals:

Ensure REMOTE mode (SEQ=TRM, REF=TRM).

FV input 0~10 V or FI input 4~20 mA set frequency.

Close S1 (forward rotation) or S2 (reverse rotation) to start. If disconnected, slow down and stop.

Chapter 4: Detailed Explanation of Core Parameters - Fine Debugging

The parameters of VS-616PC5/P5 are divided into n001~n116, and the access level is controlled through parameter n001 (password/initialization). When leaving the factory, n001=1, readable and writable n001~n035, and read-only for the rest. Set to 3 to access all parameters.

4.1 Password and Initialization (n001)

N001=0: Only n001 can read and write, the rest are read-only.

N001=1 (default): n001~n035 can be read and written.

N001=2: n001~n053 can be read and written.

N001=3: All parameters are readable and writable.

N001=8:2 wire system initialization (American standard).

N001=9:3 wire system initialization (American standard).

4.2 Operation mode selection (n002)

N002 determines the source combination for running commands and frequency references. Common settings:

3 (default): SEQ=TRM, REF=TRM (terminal control).

0: SEQ=OPR, REF=OPR (operator control).

1: SEQ=TRM, REF=OPR (terminal start stop, operator set frequency).

4.3 V/f characteristic adjustment (n010~n017)

N010="60Hz Preset": Standard linear V/f, non adjustable parameter.

N010="User defined V/f": Custom V/f curve must meet the requirement of n016 ≤ n014<n013 ≤ n011.

Main parameters:

N011 maximum frequency (50~400 Hz, default 60 Hz)

N012 maximum voltage (230V level 0.1~255 V, default 230 V)

N013 fundamental frequency (default 60 Hz)

N014 intermediate frequency (default 3.0 Hz)

N015 intermediate voltage (default 17.2 V)

N016 minimum frequency (0.1~10 Hz, default 1.5 Hz)

Variable torque loads (fans, pumps) typically use a decreasing square V/f curve, which can be manually set to n014=30 Hz and n015=57.5 V (doubled for 460V levels).

4.4 Acceleration and deceleration time (n018~n021)

N018 acceleration time 1, N019 deceleration time 1 (default 10.0 seconds)

N020 acceleration time 2, N021 deceleration time 2 (switchable through multifunctional terminals)

Set the time from 0 Hz to the maximum frequency (n011). 0.0~3600 seconds can be set, with a resolution of 1 second when ≥ 1000 seconds.

4.5 Torque Boosting and Automatic Torque Compensation

Full range automatic torque boost (n071): Automatically adjust the output voltage according to the load. Default 1.0, generally does not require adjustment. When the motor cable is too long or the motor vibrates, a fine adjustment of 0.1 step size can be made. Increasing n071 can improve low-speed torque, but excessive torque may cause overexcitation, overcurrent, or motor overheating.

Energy saving control (n096~n099): n096=1 enabled. Prevent light load stall by using n097 energy-saving gain (default optimal) and n098/n099 voltage lower limit (at 6 Hz and 60 Hz).
