(1)
The first “_” equals either “P” for the Model 940 encoder based drive OR an “R” for the Model 941 resolver
based drive.
(2)
The second “_” equals either “E” for incremental encoder (must have E94P drive) OR an “R” for the standard
resolver (must have E94R drive).
(3)
Mains voltage for operation on 50/60 Hz AC supplies (48 Hz -0% … 62Hz +0%).
(4)
Connection of 120VAC (45 V … 132 V) to input power terminals L1 and N on these models doubles the
voltage on motor output terminals U-V-W for use with 230VAC motors.
(5)
Connection of 240VAC or 120VAC to input power terminals L1 and L2 on these models delivers an equal voltage
as maximum to motor output terminals U-V-W allowing operation with either 120VAC or 230VAC motors.
(6)
Drive rated at 8kHz Carrier Frequency. Derate Continuous current by 17% at 16kHz.
(7)
Peak RMS current allowed for up to 2 seconds. Peak current rated at 8kHz. Derate by 17% at 16kHz.
