Chapter 2 Standard Specifications
16
Contact capacity :normally closed contact 5A/AC
250V ， normally open contact 3A/AC 250V ，
1A/DC 30V.
Two-way analog output, 16 signals can be selected
such as frequency, current, voltage and other, output
signal range (0 to 10V / 0 to 20mA).
At most 3-way output, there are 40 signals each way
Limit frequency, jump frequency, frequency
compensation, auto-tuning, PID control
Built-in PID regulates braking current to ensure
sufficient braking torque under no overcurrent
condition.
Three channels: operation panel, control terminals
and serial communication port. They can be switched
through a variety of ways.
Total 5 frequency sources: digital, analog voltage,
analog current, multi-speed and serial port. They can
be switched through a variety of ways.
6 digital input terminals, compatible with active PNP
or NPN input mode, one of them can be for high-
speed pulse input(0 to 100 kHz square wave); 2
analog input terminals for voltage or current input.
2 digital output terminals, one of them can be for high-
speed pulse output(0 to 100kHz square wave); one
relay output terminal; 2 analog output terminals
respectively for optional range (0 to 20mA or 0 to
10V), they can be used to set frequency, output
frequency, speed and other physical parameters.
Overvoltage protection, undervoltage protection,
overcurrent protection, overload protection, overheat
protection, overcurrent stall protection, overvoltage
stall protection, losting-phase protection (optional),
communication error, PID feedback signal
abnormalities, PG failure and short circuit to ground
protection.
Displays current temperature IGBT
Instantaneous power-
down restart
Less than 15 milliseconds: continuous operation.
More than 15 milliseconds: automatic detection of
motor speed, instantaneous power-down restart.
