4.3.1 Wiring to a host
Stop!
An additional mains isolation is required, if
• a 820X or 821X controller is connected to a host and
• a safe mains isolation (double basic insulation) to VDE 0160 is necessary.
For this, it is, for instance, possible to use an interface module which provides an additional mains
isolation (see corresponding manufacturer’s data).
For wiring, the electrical isolation of the supply voltage must be taken into account.
Tip!

• Internal voltage supply

– If the 2141 fieldbus module is to be able to communicate even if the basic device is switch
off.
• If the bus system is distributed over several control cabinets, install a separate power supply
in every control cabinet to supply all devices/fieldbus modules.
Install an equipotential bonding conductor between the control cabinets.

Prior to first switch-on of the controller, check the wiring for
• Completeness
• Short circuit
• Earth fault
Step Procedure Remarks
1. Connect the basic unit and
if available external supply for the fieldbus
module.
2. Configuration of controllers connected to
the bus
3. It should now be possible to communicate
with the drive.
4. Drive-specific settings à Operating Instructions of the basic unit
5. Enable controller à Terminal controller inhibit (CINH) = HIGH
6. Setpoint selection à The drive should be running now.
Commissioning
• Onle of the two operating status LEDs at the controller, see ^ 4-1, must be on

If this is not the case, see
• The green Vcc display must also be on, see ^ 4-1.
If this is not the case, see
Configure the controllers connected to the bus by means of an appropriate

93XX 1. If you want to control the drive via LON, configure the Lenze paramete r “Signal configuration” (C0005) for xxx3. This change can be carried out
1. The drive can be controlled through LON, if the Lenze parameter “Operating mode” (C0001) is changed from 0 to 3. This change can be made
by using the keypad or directly via LON.
• Example:
For LON Write (C0001=3), subindex: 0, value = 30000.
Please see the information about how to change parameter values of a code in chapter 6.1.2.1.
2. Terminal 28 (controller enable) is always active
the controller cannot be enabled by the LON.
3. 821X, 8200vector and 822X:
The QSP function (quick stop) is always active
A input terminal configured for QSP (default setting: not assigned) must be HIGH during LON operation (see Operating Instructions for the

• Example:
For LON Write (C0005=1013), subindex: 0, value: 10130000.

E1 must be HIGH for LON operation (see 93XX Operating Instructions).
With the signal configuration C0005=xx13, t erminal A1 is configured as voltage output. Therefore, only the following terminals must be

5.2.1 Protection against uncontrolled restart
Tip!
After an error or fault (e.g. short-term mains failure) a restart of the drive is not always wanted.
• The start condition can be changed, i.e. the drive can be inhibited by setting C0142 = 0 for
the event that
– the corresponding controller sets a fault „Message“
– the fault is active for more than 0.5 s
Parameter function:
• C0142 = 0
– Controller remains inhibited (even if the fault is not active any longer)
– The drive restarts in a controlled mode: LOW-HIGH transition at one of the inputs for
„Controller inhibit“ (CHIN, e.g. at terminal X5/28)
• C0142 = 1
– Uncontrolled restart of the controller possible

General information on parameter setting
Two different data types are transferred by the 2141 fieldbus module:
• Parameter data
• Process data,
Different communication channels are assigned to parameter and process data:
Telegram type Communication channel
Parameter data These are, for instance,
• Operationg parameters
• diagnostics information
• motor data
In general, the parameter transfer is not as
time-critical as the tranfer of process data.
Process data These are, for instance,
• Setpoints
• Actual values
Exchange between host and controller
required as fast as possible. Small amounts
of data, which are transferred cyclically.

6.1 Parameter data channel configuration
6.1.1 Parameter data
Parameter data are addressed through Lenze codes. You find a code table in the Operating
Instructions for your controller.
Lenze parameter sets
Parameter sets are for special code saving which is necessary because of different configurations
for different application processes.
The following table informs about the number of parameter sets and how to address them.
82XX 8200 vector
82XX and 8200 vector controllers have 2 and 4 parameter sets. They can be directly addressed
through LON.
They are addressed by means of a code-digit offset:
• Offset 0 addesses parameter set 1 with Lenze codes C0000 to C1999
• Offset 2000 addresses parameter set 2 with Lenze codes C2000 to C3999
• Offset 4000 addresses parameter set 3 with the
No additional parameter sets available.
If a parameter is available only once (see Operating Instructions for 82XX or 8200 vector), use t he
code digit offset 0.
Example for C0011 (maximum field frequency):
C0011 in parameter set 1: Lenze code = 11
C0011 in parameter set 2: Lenze code = 2011

Parameter changes

Lenze codes C6000 to C7999
C0011 in parameter set 3: Lenze code = 4011
C0011 in parameter set 4: Lenze code = 6011
93XX controllers have 4 parameter sets
(depending on the variant) for non-volatile
saving.
Another parameter set is in the user
memory of the controller. This is the
After switching on the controller,
parameter set 1 is automatically loaded

es of the currentparameter set will
Chan
be lost after switching off the controller.
The current parameter set is stored in
code C0003.
Only the current parameter set can be
directly addressed through LON.
The 93XX codes are listed in the
Operating Instructions and the Manual.
All changes made without storing them will
be lost after the controller is switched off.

Stop!
• For 8200 vector
– Please note that it is not allowed to write parameter data to the EEPROM.
– If you want to cyclically change parameter data, the code must be configured as follows
after every mains switching: C0003 = 0.
• For 82XX
– Please note that it is not allowed to cyclically write parameter data to the EEPROM.

6.1.2 Network variable for the parameter data channel
The network variables nviParamReq, nvoParamRes and nvoLongRes
• enable parameter setting and diagnostics.
• allow access to all Lenze parameters (codes).
The input network variable nviParamReq allows to send a read or write request to the drive.
With parameters with a length of up to 4 bytes, the response is output through the output network
variable nvoParamRes.
With parameters bigger than 4 bytes, the response to a read request is output through the network
variable nvoLongRes.
