RW: Winding resistance per winding (in CDS303 parameter list)
RLA: Rated load current
MMT: Maximum must trip current
Note that parameter 1-30 in the frequency converter settings reects the winding resistance per winding. This is not the same value
as measured at the motor terminals.
Because VZH compressors are powered by a
frequency converter, the mains frequency, 50 or
60 Hz, is no longer an issue. Only the mains
voltage is to be taken into account. With 3 motor
voltage codes, the most common mains voltages
and frequencies are covered. Never connect the
VZH compressor directly to the mains power
supply.
On VZH all data published and in our polynomials
are based on 208V frequency converter supply
for code J and 400V frequency converter supply
for code G.
When having a supply of 230V, 380V or 460V the
following coecients must be applied:
I
460
= 0.87* I
400
I
380
= 1.05* I
400
I
230
= 0.90* I
208
There is no modication for cooling capacity and
power input.
Since data published for code H is based on 575V
frequency converter supply, thus there will be no
coecients modication applied for H code.

Rated Load Amp value is the current value at maximum load, in the operating envelope, and at
maximum speed. We have agency (UL, CE, etc) approved at our max operating, the drive can limit the
amps but the OEM is responsible for that submittal to agency.
RLA (Rated Load Amp)
MMT (Maximum Must Trip
current)
The Maximum Must Trip current is dened
for compressors not equipped with their
own motor protection. This MMT value is the
maximum at which the compressor can be
operated in transient conditions and out of
the operating envelope. The tripping current
of external overcurrent protection, in this case
preprogrammed in the drive, never exceeds the
MMT value.
For VZH compressors, according to UL
requirements, MMT value is 125% of RLA. This
value is printed on the compressor nameplate.
