Delta Electronics VFD-E manual Speed search function and synchronize with the motor

			Chapter 4 Parameters
	Settings	Function	Description
			Parameter value 09 programs a Multi-function Input Terminals for
			external Base Block control.
		External Base	NOTE: When a Base-Block signal is received, the AC motor
9		Block	drive will block all output and the motor will free run. When
		(Refer to Pr.08.06)	base block control is deactivated, the AC drive will start its
			speed search function and synchronize with the motor
			speed, and then accelerate to Master Frequency.
10		UP: Increase	Increase/decrease the Master Frequency each time an input is
		Master Frequency	received or continuously when the input stays active. When both
			inputs are active at the same time, the Master Frequency
		DOWN: Decrease
11			increase/decrease is halted. Please refer to Pr.02.07, 02.08. This
		Master Frequency	function is also called “motor potentiometer”.
			Parameter value 12 programs one of the Multi-function Input
12		Counter Trigger	Terminals MI7 ∼ MI12 (Pr.11.06~Pr.11.11) to increment the AC
			drive’s internal counter. When an input is received, the counter is
			incremented by 1.
13		Counter Reset	When active, the counter is reset and inhibited. To enable
			counting the input should be OFF. Refer to Pr.03.05 and 03.06.
			Parameter value 14 programs one of the Multi-function Input
14		External Fault	Terminals MI7 ∼ MI12 (Pr.11.06~Pr.11.11) to be External Fault
			(E.F.) inputs.
15		PID function	When an input ON with this setting is ON, the PID function will be
		disabled	disabled.
			AC motor drive will stop output and the motor free run if one of
16		Output Shutoff Stop	these settings is enabled. If the status of terminal is changed, AC
			motor drive will restart from 0Hz.
17		Parameter lock	When this setting is enabled, all parameters will be locked and
		enable	write parameters is disabled.
