		Other	LED comes on with charging voltage applied.
	Acceleration/Deceleration time		0-60s (Variable setting) Acceleration time and deceleration
Control			time can be set independently.
	Voltage frequency characteristics		Setting of maximum frequency/base frequency is variable.
	Restart after momentary power failure		"Automatic restart" setting makes it possible to keep motor
			running and restart drive in case of a momentary power failure.
	High Limiter & Low Limiter		Upper limit and lower limit of frequency can be set.
	Bias setting		Bias setting is possible with respect to analog frequency setting.

Braking	DC brake		Brake starting frequency: 3 Hz (fixed)
			Setting of braking current / braking time is variable.
	Overload		Detects overload current and stops drive.
	Momentary overcurrent		Protects drive In case of ground fault (detects at start) and
			short circuit of output circuit.
	Overvoltage		Detects overvoltage of DC bus and stops drive.
Protection	Overheating of cooling element		Detects abnormal temp. rise of cooling element and stops drive.
	Motor protection		Protects standard 4-pole motor and forced-air cooled motor by
			means of electronic thermal overload relay.
	Alarm protection		Outputs contact signal in case of a trip for protection
			(1c contact capacity: AC250V 0.3A			cos = 0.3)
