3)Sink logic/source logic input

Switching between sink logic and source logic (input terminal logic) is possible.

6.2.4Jog run

• Function

The VF-nC1 inverter is capable of jog operation if its input terminal selection function is so set. Jog run refers to jogging or inching a motor. Input of a jog run signal causes the VF-nC1 inverter to produce a jog run signal (fixed at 5Hz) for 0.1 seconds (fixed), regardless of the specified acceleration time. Cutting off a jog run signal causes the motor to coast to a stop.

■The motor continues to run in jog mode as long as both the jog run signal and the operation signal are put out. To enable the jog run function, you need to assign the jog run function (4) to an unassigned input terminal.

For the VF-nC1 inverter, all settings for jog run are fixed, as shown below.

Jogging frequency	5Hz
Jogging stop pattern	Coast stop
Acceleration time	0.1 sec.

<Examples of jog run> (When the jog run function is assigned to the S1 terminal: H=4)
				6
	S1-CC (JOG) ON + F-CC ON: Forward jog run
	S1-CC (JOG) ON + F-CC ON: Reverse jog run
（	Normal operation frequency signal input + F-CC ON: Forward run		）
（	Normal operation frequency signal input + R-CC ON: Reverse run		）
	Output frequency [Hz]

S1 (JOG)-CC

Normal operation frequency setting signal input

•The jog run terminals (S1-CC) are enabled when the operation frequency is below 5Hz. They do not function when the operation frequency is higher than the jog run frequency (5Hz).

•The motor continues to run in jog mode while the jog run terminals (S1-CC) are electrically connected.

•Jog run has priority, and it continues even if any other operation command is entered during operation.

Note: During jog run, the VF-nC1 inverter may produce an Low-speed detection signal (LOW) signal but not Designated frequency reach signal (RCH) signal, and therefore PI control is not performed.

6.2.5Switching between control logics

H : Sink/Source selection

• Function

This parameter is used to switch between sink logic (negative common) and source logic (positive common).

■Parameter setting

Title	Function	Adjustment range	Default setting
		Adjustable within a range of 0 to 200
H	Sink/Source selection	0: Sink	0
		100: Source
		Others: Invalid

*The value is changed according to the set-up parameter condition. (VFNC1 (S)-□□□□P□-W type) 0 (sink) for VFNC1 (S)-□□□□P□type.
