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.

Starting torque [%] 150% for 60 seconds.
Braking torque 5 [%] 150% 1 min. 100% 1 min. 50% 1 min.
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
