Numerator and denominator factors may take on values between 1 and 10,000. 
 
 

f) Drag error 

 

During a positioning run, the device compares the computed target position with the 
current actual value. If the 

difference is larger than the ‘drag error’ value (HR 59), the 

device sets the corresponding bit in the status word. This situation is especially likely 
to occur if external factors (required torque, voltage to motor too low) prevent the 
device from achieving the target rpm. 
 
 

g) Abort run when the master fails 

 
If the connection to the master is interrupted during a positioning run, the master 
cannot abort an actual run. An automatic run abort can be generated by using HR 40. 
A value greater than 0 sets the time within the Master must send a new and valid 
request to keep the connection alive. A timout in the device will result in aborting the 
run. 
 
 

h) Reference runs 

 
The PSE2xxMod positioning system is equipped with an absolute or partially absolute 
measuring system, therefore there’s no need for a reference run when powering on 
the drive. However, if in certain cases a reference run onto a hard block should be 
desired (e.g. uniquely when installing the drive at a machine), the course of action 
should be the following: 
 
1)  Before commanding the reference run the following settings have to be carried 

out: 

set the maximum torque (HR 77) and the maximum start-up torque (HR 76) to 
max. 10% of the nominal torque 

set the rpm limit for aborting run (HR 70) to 60 

set the time elapsed until speed falls below rpm limit for aborting run (HR 83) 
to 100 
(The span of time in which the drive trys to get over the block, decreases: 
With the reduced values the positioning will be aborted if the speed stays 
below 60% of the target speed for longer than 100ms. By default, these 
values are 30% and 200ms.) 

set the corresponding upper and lower limit (HR 52/53 or HR 54/55) in a way 
that the block location lays considerable within the area between the upper 
and lower limit 
(O

therwise there’s the danger that the block is located within the positioning 

window a

nd consequently won’t be recognized.) 

Where appropriate, reduce the target speed for manual run (HR 69). 

2)  Now start the reference run as manual run (set bit 0 or 1 in the control word). 
3)  Wait for the drive moving (bit 6 in the status word is set).
