Onboard multiple
preset speeds
JOG frequency range: 0.00–50.00 Hz
JOG acceleration/deceleration time: 0.0–6500.0s
It implements up to 16 speeds via the simple PLC
function or combination of S terminal states.
Onboard PID
Auto voltage
regulation (AVR)
It realizes process-controlled closed loop control
system easily.
It can keep constant output voltage automatically when
the mains voltage changes.
Overvoltage/
Overcurrent
stall control
The current and voltage are limited automatically
duringthe running process so as to avoid frequent
tripping due to overvoltage/overcurrent.
High-speed current
limiting function
Minimize over-current fault and protect normal operation
of AC drive.
Torque limit and
control
It can limit the torque automatically and prevent fre-
quent over current tripping during the running process.
Torque control can be implemented in the CLVC mode.
High performance
Power dip ride
through
Control of asynchronous motor and synchronous motor are
implemented through the high-performance current vector
control technology.
The load feedback energy compensates the voltage
reduction so that the AC drive can continue to run for
a short time.
Rapid current limit
It helps to avoid frequent overcurrent faults of the
AC drive.
Timing control
Time range: 0.0–6500.0 minutes
Individua-
lized
functions
Multiple
communication
protocols
It supports communication via Modbus-RTU, PROFIBUSDP,
CANlink and CANopen.
Motor overheat
protection
The optional I/O extension card enables AI4 to receive
the motor temperature sensor input (PT100, PT1000) so
as to realize motor overheat protection.
Item
S p ecifi c a t i ons
Multiple encoder
types
It supports various encoders such as differential
encoder, open-collector encoder, resolver, UVW encoder,
and SIN/COS encoder.
Advanced
background
software
It supports the operation of AC drive parameters and
virtual oscillograph function, via which the state
inside the AC drive is monitored.
Running
command source
• Operation panel
• Control terminals
• Serial communication port
You can perform switchover between these sources in
various ways.
Frequency source
Auxiliary
frequency source
There are a total of 10 frequency sources, such as
digital setting, analog voltage setting, analog current
setting, pulse setting and serial communication port
setting. You can perform switchover between these
sources in various ways.
There are ten auxiliary frequency sources. It can
implement fine tuning of auxiliary frequency and
frequency synthesis.
