Basic
func
tions
Resolution of input frequency Digital setting: 0.01 Hz
Analog setting: maximum frequency x 0.025%
Operation Operation
command
Independent dual channel and dual channel, which can be switched
freely
Provides different start/stop sources (terminal, operating panel,
communication, custom, connector).
Provides standard control word.
Frequency
reference
Independent dual channel and dual channel, which can be switched
freely
Provides various sources (communication, operating panel, analog,
connector, and so on).
Supports main frequency, auxiliary frequency, and various operations
(addition, subtraction, multiplication, Max., and Min.).
Supports additional frequency.
Supports multi-level frequency limits.
Auxiliary
frequency
reference
Supports various auxiliary frequency references and allows fine-tuning of
the auxiliary frequencies and frequency synthesis.
Standard
command
word
Normal start/stop (OFF1)
Emergency stop (OFF2)
Quick stop, stop with maximum capability (OFF3)
Operation enable, operation pause
Torque
reference
Multiple torque reference sources: digital reference, analog voltage
reference, analog current reference, pulse reference, multi-reference,
PID, simple PLC, and communication, which can be switched through
multiple ways
Start/Stop
mode
Dual channel, which can be switched freely
Supports six different start/stop modes (single-wire mode, two-wire
mode 1, two-wire mode 2, two-wire mode 3, three-wire mode 1, three-
wire mode 2)
Acceleration/
Deceleration

Supports different unit settings (Hz, rpm, rated %, maximum speed %).
Supports free per-unit conversion.
Supports custom limit.
Ramp transition function When speed references are sent through communication cyclically,
automatic interpolation is supported to rectify command discontinuity
caused by communication intervals, ensuring smooth operation.
Output limit Torque limit, power limit, current limit, maximum/minimum torque limit,
and speed limit

Display and
operations on
the operating
panel
LED operating
panel
Used to display and change parameters and display drive status (forward
run, reverse run, stop, operating panel/terminal/communication control,
speed/torque control).
Key lock and
function
To prevent inadvertent operations, keys on the operating panel can be
locked partially, and functions with limited availability range can be
assigned to some keys.
Commissioning software tool The commissioning software (iFA Drive/InoDriverShop) supports
uploading and downloading drive parameters and oscilloscope
functions. You can monitor internal status of the drive through the
oscilloscope.
Function logic is presented using data flow diagrams, enabling manual-
free commissioning.
This helps reduce the learning cost and shorten commissioning time.
Parameter protection Supports parameter access write protection to prevent inadvertent
parameter modification.
User password (parameter lock) Supports user-defined passwords to protect parameter accessibility.
Parameter access levels Standard: default level with access to commonly used function
parameters
Extended: Extended with non-frequent function parameters
Expert: Parameters for experts, which can be set with a password
