Chapter 6 Operation from PROFINET
6.1 Precautions for use
Check the Inverter settings for proper Inverter behavior before actually operating the Inverter
remotely via the network.
The product will be used to control an adjustable speed drive connected to high voltage sources
and rotating machinery that is inherently dangerous if not operated safely. Interlock all energy sources,
hazardous locations, and guards in order to restrict the exposure of personnel to hazards. The
adjustable speed drive may start the motor without warning. Signs on the equipment installation must
be posted to this effect.
A familiarity with auto-restart settings is a requirement when controlling adjustable speed drives.
Failure of external or ancillary components may cause intermittent system operation, i.e., the system
may start the motor without warning or may not stop on command. Improperly designed or improperly
installed system interlocks and permissions may render a motor unable to start or stop on command.
6.2 Setup of the WJ200 / WL200 for commissioning
Before commissioning, prepare the Inverter and WJ-PN by following the setting example below.
6.2.1 Setting of the inverter mode (When WJ200 / WL200 is
connected to standard IM.)
Set the Inverter mode to Std. IM by first setting b171 = 1 and then b180 = 1.
When WJ200 / WL200 is connected to PM, you need to set b171 = 3.
6.2.2 Initialization of the inverter
First of all, please set b084 to 04(Clears trip history and initializes all parameters and EzSQ
program), next set b085 to 01(area A), and then set b094 to 00(All parameters), and next set b180 to
01(Perform initialization), and then initialization of the inverter will be started.
6.2.3 Constant Torque mode/Variable Torque mode selection
In case of WJ200, Set b049 to 00 (b049 = 00: Constant Torque mode).
In case of WL200, you don't need to set b049 because WL200 supports only Constant Torque
mode and doesn't support b049.
After the above-mentioned setting is completed, please set the parameter A001, A002, A004, A038,
A039, A093, b031, C001 - C007, C042, C043, C102, P044, P045, P160 - P179 and P200 according
to the table in "7.2: Parameter setting of WJ200 / WL200". When you set parameters with Operator
or PC (ProDriveNext), you need to turn OFF the inverter. After the power supply of the inverter
becomes OFF, please turn ON the inverter and check that WJ-PN communicates by PROFINET.
Please refer to data example of the WJ200 / WL200 operating in the PROFINET communication
from the next page.
