If the XPI file is loaded the parameter
El. Gear Reference Frequency
125 can be ad-
justed for the reference value input of the electronic gear. Practical settings for opera-
tion without optional System bus are:
Operation mode
Function
80 - Freq. Speed Sensor 1
Reference value source is the speed sensor 1
frequency signal.
81 - Freq. Speed Sensor 2
Reference value source is the speed sensor 2
frequency signal.
288 -
Repetition Frequency
Input
Reference value source is the frequency signal at
the repetition frequency input.
Note: It is possible to use Systembus values as reference value. Change the para-
meter
El. Gear Reference Frequency
125 accordingly to the Systembus PDO,
which receives the reference value.

Position Control
Activation of the overriding position control for the electronic gear is particularly useful
if a synchronization without drift between the Master and the Slave is required for
longer periods of time. Inaccuracies which result from rounding errors in the calcula-
tion of the gear factor are eliminated. Additionally, an offset angle relative to the mas-
ter drive can be set at the slave drive.
The reference value for the position controller is specified via the repetition frequency
input or the speed sensor input of the slave or via the System Bus.
To enable position control, operation mode "11 – fixed with position control" must be
selected for parameter
Operation Mode
689.
If an XPI file x15 is loaded to the software VPlus, e.g. swc215.xpi for the configura-
tion 215, you can adjust parameter
Position Reference Value
147 to the reference
value source for the position control. Practical settings for operation without optional
System bus are:
Operation mode
Function
82 - Position Speed Sensor 1 Reference value source is the speed sensor 1
input.
83 - Position Speed Sensor 2 Reference value source is the speed sensor 2
input.
Via parameter
Position Actual Value
148, you can adjust the actual value source for
the position control. Practical settings for operation without optional System bus are:
Operation mode
Function
82 - Position Speed Sensor 1 Actual value source is the speed sensor 1 input.
83 - Position Speed Sensor 2 Actual value source is the speed sensor 2 input.
Example for parameterisation:
Reference frequency value at speed sensor 1 input
Speed sensor feedback at speed sensor 2 input (expansion module required)
