Drive Functional Specification – ViX250AE, ViX500AE

Parameter Value
Maximum output current
Maximum continuous power drawn from the
supply
ViX500: 5A RMS continuous
15A RMS peak (2 seconds max.)*
ViX250: 2.5A RMS continuous
7.5A RMS peak (2 seconds max.)*
6.3A at 80V (500VA)
Motor HV supply input
(No reverse polarity protection, HV
reversal WILL damage the drive)
ViX500: 48 – 80V DC +5% -15%
ViX250: 24 – 80V DC +5% -15%
Minimum PSU capacitance ViX500: 6,600µF
ViX250: 3,300µF
Controller supply input 24V DC +10% to –15%
Protection Short circuit (phase-to-phase, phase-to-
ground)
Motor HV over and under voltage trip
(HV over voltage 98V nominal)
Drive over-temperature
Motor over-temperature (motor dependent)
24V reverse polarity
Commutation encoder fault
Resolver fault
Temperature protection (motor protection
depends upon the type used) see Note 1. I2t circuit protects motor and drive from
excessive dissipation
Motor current limit Selectable by software
Motor inductance range 0.5 to 10 mH For lower inductance motors
consult Digiplan
Fault output NPN open-collector output, normally low,
active high
Enable input 24V input with pull-up resistor (can be
software set to be active high or active low)
LED status indicators (tri-colour) HV/feedback fault
Drive fault
Comms. status
