* 1.
Standard braking torque is 125%. Because of the limited resistor power, the longest operation time for 10% ED is 10 seconds
(on: 10 seconds / off: 90 seconds).
* 2.
Calculation for braking torque is for a four-pole motor 1800 rpm.
* 3.
Resistors of 400 W or lower should be fixed to the frame and at a surface temperature below 250°C.
Resistors of 1000 W and above should be fixed on a surface with temperature below 600°C.
NOTE
1.
Select the resistance value, power and brake usage (ED %) according to Delta rules.
Definition for Brake Usage ED%
Explanation: ED (%) is defined to allow enough time for the
brake unit and brake resistor to dissipate the
heat generated by braking. Recommended
cycle time T0 is one minute.
