Toshiba VF-A7 instruction manual About operation

■About operation

	Danger	Reference
	-Do not touch any inverter's terminal when it is energized even if the motor	3.
	is standstill, or you could get a shock.	3.
	-Do not operate switches with a wet hand or not put a wet cloth on the
Prohibited	inverter, or you could get a shock.	3.
	-Do not get near the alarm-stopped motor when the system is in retry
	mode, or you could get an injury.
	Take safety measures, for example, attaching a cover to the motor, to
	protect persons against accidents when the motor unexpectedly restarts.	6.21
	-Don't set the motor constant 3 (exciting inductance:) as 1/2 or less
	value of default setting value. If the motor constant 3 (exciting
	inductance :) is set as extremely small value, the stole prevention
	function	6.25.2
	will incorrect-operate and will raise output frequency.
	-Don't set the stole prevention level() as extremely small value.
	When the stole prevention level() is set as motor no-load current
	or value lower than it, the stole prevention function always operates. And
	if it is judged as regeneration mode, frequency will be raised.
	Please do not set the stole prevention level() to 30% or less in
	the usual usage.
	-Do not turn on the power before attaching the front cover. When the	3.
	inverter is installed in a cabinet with the inverter's front panel detached,	9.
	always close the door of the cabinet before turning on the power.
Mandatory	Turning on the power with the cover or the door left opened could lead to
	an electric shock.
	-Turn off the operation signal before resetting the inverter after trouble, or	3.
	the motor unexpectedly restarts, causing injury to persons.
	Warning	Reference
	-Operate the motor always within the allowable operation range. (Refer to
	the motor’s instruction manual for the allowable operation range.)	3.
Mandatory	Failure to do so could cause injury to persons.

When selecting the sequence that automatically restarts the motor after

recovery from a momentary power failure (Applicable to inverters)

	Warning	Reference
	-Do not get near the motor or the machine.	6.13.1
	The motor and the machine unexpectedly restart after recovery from a
	momentary power failure.
Mandatory	-Stick caution labels to the inverter, the motor and the machine, to prevent
	accidents due to an unexpected restart of them after recovery from a
	momentary power failure.
