FEEDBACKS 
SETUP::MOTOR CONTROL::FEEDBACKS 
Designed for all Motor Control Modes. 
The FEEDBACKS block allows you to view speed feedback and motor current related diagnostics.  
Parameter Descriptions 
QUADRATIC TORQUE 
PREF: 70.01  Default: FALSE  Range: FALSE/TRUE 
When TRUE, selects QUADRATIC allowing higher continuous ratings with less overload capability. Quadratic Torque 
operation is especially suited to fan or pump applications. When FALSE, selects CONSTANT duty. 
OVERLOAD LEVEL 
PREF: 70.20  Default: HIGH  Range: See below 
This reduces I*t limit for shaftless printing applications. However, with OVERLOAD LEVEL set to LOW, no pwm 
frequency reduction occurs during overload conditions. 
Enumerated Value :  Level 
0 : LOW    130% for 60s : sets the I*t limit 
1 : HIGH    150% for 60s : sets the I*t limit 
DC LINK VOLTS 
PREF: 70.02  Default: —. V  Range: —. V 
This shows the voltage across the dc link capacitors. 
TERMINAL VOLTS 
PREF: 70.03  Default: —. V  Range: —. V 
This shows the rms voltage, between phases, applied by the Drive to the motor terminals.
