Encoder type

Encoder type "not available"
An encoder type setting of "not available" for Encoder x means that Axis x does not exist, or
that it is not to be operated. User data transmitted for this axis in the PROFIBUS message
frame are empty.
Encoder type TTL
Encoder parameters:
● Resolution
Note
In the case of spindles with a low-resolution encoder, the actual-value characteristic
(incrementing) may be displayed in a non-linear fashion. The incrementing that is visible on
the actual-value display is the result of the speed resolution (RR), where:
• RR: 60000 / ( T
• RR (speed resolution): [(revolutions/min) / encoder pulse]
• T
• ER (encoder resolution): [Encoder pulse / revolution]
• PM (pulse multiplication)
Example:
T
DP
ER (encoder resolution): 2500 pulses/revolution
PM (pulse multiplication): 4
RR = 60000 ( 2*2500*4) = 3 (revolutions/min) / encoder pulse
44

(position control cycle clock = PROFIBUS cycle clock): [ms]
DP
(position control cycle clock = PROFIBUS cycle clock): 2 ms
