Chapter 5 Function Code
Cancel constant peripheral speed control Hz/LSC (Function code E01 to E09, data = 70)
With
Hz/LSC signal, the constant peripheral speed control can be canceled. When cancelled, the frequency
compensation by PI calculation becomes zero; therefore, compensation of thickening of a take-up roll,
resulting in increasing speed. Use this function to temporarily interrupt the control for repairing a thread
break, for example.
Table 5.4-173
Hz/LSC Function
OFF
Enables constant peripheral speed control (depending on d41 setting)
ON
Cancel constant peripheral speed control (V/f control, without compensation for a
take-up roll getting bigger)
Constant peripheral speed control frequency in the memory LSC-HLD (Function code E01 to E09, data =
71)
While
LSC-HLD signal is on under constant peripheral speed control, stopping the inverter (including an
occurrence of an alarm and a coast-to-stop command) or turning off
LSC-HLD saves the current frequency
command compensating for a take-up roll getting bigger, in the memory. At the time of restarting, the saved
frequency command applies and the inverter keeps the peripheral speed constant.
Table 5.4-174
LSC-HLD Function
OFF
Disable (No saving operation)
ON
Enable (Saving the frequency command compensating for a take-up roll getting
bigger)
Shutting down the inverter power during an operation stop loses the frequency compensation data
saved in the memory. At the time of restart, therefore, the inverter runs at the frequency without
compensation so that a large overshoot may occur.
d51 to d55
d68, d69,
d99
For manufacturers
Function codes d51 to d55, d68, d69 and d99 appear on the monitor, but they are reserved for particular
manufacturers. Unless otherwise specified, do not access these function codes.
d59 to d63
d71 to d78
Command (Pulse Train Input)
(Pulse Input Method, Encoder Pulse Number, Filter Time Constant, Pulse
Compensation Factor 1,
Pulse Compensation Factor 2) (See F01)
Simultaneous Operation Function Selection
For the pulse train input, see the section describing the function code F01.
It is possible to execute the synchronization operation by using PG interface card
(OPC-G1-PG/OPC-G1-PG22). For details, see the PG Interface Card Instruction Manual.
