Blade Position – 

This shows the current position of the blade in degrees relative to the home offset 

position.  To set either of the positions to the 
right, move the blade to the desired position 
and press the arrow to save the position.  A 
confirmation will appear in the numeric field 
and you must accept or cancel. 

Reverse Home Direction

 – This position sets the position of the blade where it will go backwards or 

forwards to home.  If the position is lower than this value it goes backwards to home, otherwise it 
goes forward to home.  When homing on power up, the blade always homes in the forward direction.  
If there is product in the path of the blade, it will obstruct the blade or it will be cut.  If 2 blades are 
installed and the system is stopped improperly with the Emergency  Stop, the blades will stop 
immediately where they are.  When the system is powered up, there is a 50% chance that the blades 
will need to move through the product to get home and therefore the product will need to be removed 
to allow the blade to move to home. 
 

Blade at Cut Position – 

This sets the position of the blade where it counts the product.  It is usually 

set when it is completely through the product. 

 

USE DYNAMIC TUNING 

Dynamic tuning is used to change tuning parameters when 
running between on-line and continuous.   
 

On Demand 

operation requires an extremely fast response with large acceleration torques being 

used.   

Continuous

 mode prefers a slower response to maintain the set speed in a tighter tolerance.   

 
The values shown in the window can be adjusted to account for changing loads and aging of the 
equipment.  Be very careful changing any of these.  Improper settings could cause the servo to 
become unstable, loose torque or continuously fault.  Dynamic tuning can be turned on and off with 
the button.  The servo will use the parameters that were running when it was turned off.

 

 

SERVO MOTOR DATA

– These settings are for reference only.  The 

values are read by the drive and depend on the equipment installed. 

Gear Ratio 

-  Shows the gear box attached. 

Rated Servo Speed

  - Rated speed of the motor at rated torque at 400V.  

It can be affected by the ambient temperature and supply voltage. 

Max Servo Speed 

– This is the maximum possible speed that the motor 

can obtain though torque will be reduced from the nameplate rating. 

Motor Temp

 – The temperature of the motor.  Most motors can handle  

temperatures up to 140C.  Frequent heating and cooling of the motor can 

     

    cause premature damage.
