5.3
5.3.4 Setup with MacTalk
From firmware version 4.00 the closed loop control is available, if either the H2 or H4
encoder option is installed. Only motors with serial number 173000 or higher support
the closed loop feature.
The closed loop function is by default enabled, also the current control is by default en-
abled.
Parameter explanations:
Enable closed loop
Check this field to activate the overall closed loop feature. Can be activated/deactivated
on the fly and have immediate effect. Default: inactive.
Enable current control
Check this field to add current control. The current control will increase/decrease the
current proportional to what is needed for driving the motor load. Can be activated/de-
activated on the fly and have immediate effect. Default: inactive.
Allowable over speed (0-100%) and Follow error before overspeed
Allows the motor to run with a higher velocity if the encoder position deviate from the
theoretical position by more than "Follow error before overspeed" counts.
The default for "Allowable overspeed..." is 0% which means that the maximum speed
will never exceed the "Max velocity" setting.
The default for "Follow error before overspeed" is 5000 counts.
