REGEN.TEXT

Description

REGEN.TEXT is the time-to-fault when input power steps from 0 to 150% of REGEN.WATTEXT. REGEN.TEXT sets the thermal time constant of the algorithm used to protect the regeneration resistor from overheating and failing. The drive's regen resistor protection algorithm continuously calculates the power dissipated in the resistor and processes that power value through a single pole low pass filter to model the regen resistor's thermal inertia. When the filtered regen power on the output of the filter (REGEN.POWERFILTERED) exceeds REGEN.WATTEXT, a fault occurs. REGEN.TEXT sets the time constant of this thermal inertial filter = (REGEN.TEXT/1.1).

REGEN.TEXT can often be found directly on power resistor data sheets. On the data sheet find the peak overload curve and then find the safe allowed time to be at 150% of the regen resistor's continuous power rating. Set REGEN.TEXT to this value in seconds. Another way regen resistor peak overload capability is often specified is by giving the energy rating in joules of the resistor. If you have the energy rating joule limit E then:

REGEN.TEXT = (1.1)*((E in joules)/REGEN.WATTEXT)

Example

The external regen resistor is rated for 250 W continuous, is 33 ohm, and has a joule rating of 500 joules. To use this resistor, the drive settings become:

REGEN.TYPE = -1 (External Regen)

REGEN.REXT = 33

REGEN.WATTEXT = 250

REGEN.TEXT = (1.1)*(500 j)/(250 W) = 2.2 sec
