Goodrive30 Series VFD Communication protocol
-134-
The service life of the Electrically Erasable Programmable Read-Only Memory (EEPROM)
may be reduced if it is frequently used for storage. Some function codes do not need to be
stored during communication. The application requirements can be met by modifying the
value of the on-chip RAM, that is, modifying the MSB of the corresponding function code
address from 0 to 1. For example, if P00.07 is not to be stored in the EEPROM, you need
only to modify the value in the RAM, that is, set the address to 8007H. The address can be
used only for writing data to the on-chip RAM, and it is invalid when used for reading data.
7.4.2 Description of other function addresses
In addition to modifying the parameters of the VFD, the master can also control the VFD, such
as starting and stopping it, and monitoring the operation status of the VFD. The following table
describes other function parameters.
Communication-based
control command
Communication-based
value setting
Communication-based frequency setting
(0–Fmax, unit: 0.01 Hz)
PID setting, range (0–1000, 1000
corresponding to 100.0%)
PID feedback, range (0–1000, 1000
corresponding to 100.0%)
Torque setting (-3000–+3000, 1000
corresponding to 100.0% of the motor
rated current)
Setting of the upper limit of the forward
running frequency (0–Fmax, unit: 0.01
Hz)
Setting of the upper limit of the reverse
running frequency (0–Fmax, unit: 0.01
Hz)
Upper limit of the electromotion torque
(0–3000, 1000 corresponding to 100.0%
of the motor rated current)
