MM Application Possibilities
2.9.4 Settings
It is possible to use a combination of external 4-20mA servomotors and Autoflame servomotor, for
example, channel 1 can be set as an Autoflame servomotor and channel 2 can be set as an external
4-20mA servomotor. The degree of accuracy when using an external 4-20mA servomotor via a
Universal IO module is 0.5
o
, in comparison to the accuracy level of 0.1
o
which is possible on the
Autoflame servomotor. The control method for each servomotor can be set by the following options:
Option
Mk8 MM
86
Channel 1 Servo Control Method
87
Channel 2 Servo Control Method
88
Channel 3 Servo Control Method
89
Channel 4 Servo Control Method
Expansion Option
Mk8 MM
81
Draught Servo Control Method
The IO module must be configured for ID 1. Please refer to the Autoflame PC Software Guide for
more information. The MM will automatically configure all other settings in the IO module unit required
for operation. Please note that mixed IO software version 3.01 or above is required.
2.9.5 Commissioning
Figure 2.9.5.i Commissioning External 4-20mA Servomotor
The commission procedure for the Mk8 MM with external 4-20mA servomotors follows the normal
commissioning procedure, with the positions displayed in angular degrees. In run mode, the
servomotor screens show the same information as that displayed for Autoflame servomotors.
