Where the first factor can be set on parameter IPA 11398 Mstr/Slv PPR Ratio, while the second can be
calculated as integer numbers ratio by using gear manufacturer's data.
It can be obtained the following:
1
427616
2
285525
And finally
Mstr/Slv PPR Ratio = 0.5
Ratio 1 Num = 427616
Ratio 1 Denom = 285525.

7.2 Startup, tuning and performance check

General notes about project
-
Electrical shaft application is not suitable for systems where master and slave(s) are coupled by rigid
mechanical connection.
-
Drives must be equipped with braking units and braking resistors.
-
Slave full scale speed must be higher than master one. In case of asynchronous motors, slave
motor available torque in deflux mode speed range must be checked.
-
"External Fault" signal from slave to master drive should always be connected, in such a way that
master can stop as soon as slave drive fault occurs.
-
Some applications (e.g. multi-column hoists) require all drives and motors same type.
-
In case of external master encoder, use components with maximum resolution possible (preliminary
check that maximum frequency input limit for ADVencoder option boards – 200 kHz for TTL line
driver – is not overtaken).
Preliminary operations:
-
Check cabling, commands assignements and safety cut-offs.
-
Disconnect motors from driven mechanics.
-
Separately startup master and slave(s) drives in "Flux Vector Closed Loop" regulation mode.
-
Tune and test dynamic response of both drives' speed loops.
-
Activate Electrical Shaft application on each slave drive and check general parameters (see section
4.4)
-
Calculate and set slave gear ratio
-
Check master encoder speed and position reading from slave drive when master is moving:
In case of master rotary encoder, check IPA 5150 Encoder 2 speed and IPA 5162 Encoder
2 position on slave drive
In case of Fast Link master, check parameters IPA 5750 FL Fwd 1 mon and IPA 5752 FL
Fwd 2 mon
-
With SERVO PID parameters set as default, check slave drive response during synchronous
operation (engaged to master): enable master and slave, engage slave (ELS Engage ON), move
master motor (also manually) and check that slave is correctly "copying" master movement.
Electrical shaft tuning:
-
Set PID gains to zero (IPA 11200, 11202, 11204).
