Toshiba VF-FS1 instruction manual Setting of frequency with the input from an external contact

E6581381

6.5.3Setting of frequency with the input from an external contact

H : External contact input - UP response time

H : External contact input - UP frequency steps

H : External contact input - DOWN response time

H : External contact input - DOWN frequency steps

H : Initial up/down frequency

H : Change of the initial up/down frequency

•Function

These parameters are used to set an output frequency by means of a signal from an external device.

	Title	Function		Adjustment range	Default setting
6
	H	External contact input - UP response	0.0	- 10.0 (s)	0.1
		time
	H	External contact input - UP frequency	0.0	- FH (Hz)	0.1
		steps
	H	External contact input - DOWN	0.0	- 10.0 (s)	0.1
		response time
	H	External contact input - DOWN	0.0	- FH (Hz)	0.1
		frequency steps
	H	Initial up/down frequency	LL - UL (Hz)		0.0
		Change of the initial up/down	0: Not changed
	H		1: Setting of H changed		1
		frequency
			when power is turned off

*These functions take effect when parameter HOQF (frequency setting mode selection 1) is set to  or parameter H (frequency setting mode selection 2) is set to  is enabled.

■Adjustment with continuous signals (Parameter-setting example 1)

Set parameters as follows to adjust the output frequency up or down in proportion to the frequency adjustment signal input time:

Panel frequency incremental gradient = H/H setting time Panel frequency decremental gradient = H/H setting time

Set parameters as follows to adjust the output frequency up or down almost in synchronization with the adjustment by the panel frequency command:

H = H = 1

(HJ/CEE (or H)) ≥ (H/H setting time)

(HJ/FGE (or H)) ≥ (H/H setting time)
