T – is the slow loop sampling period expressed in [s]. You can read this value in the “Advanced”
dialogue, which can be opened from the “Drive Setup”.
6.5. Current units
The internal current units refer to the motor phase currents. The correspondence with the motor
currents in [A] is:
] IU [ Current
Ipeak
] A [ Current
×

=
65520
2
where Ipeak – is the drive peak current expressed in [A]. You can read this value in the “Drive
Info” dialogue, which can be opened from the “Drive Setup”.
6.6. Voltage command units
The internal voltage command units refer to the voltages applied on the motor. The significance of
the voltage commands as well as the scaling factors, depend on the motor type and control
method used.
In case of
brushless motors
driven in
sinusoidal
mode, a field oriented vector control is
performed. The voltage command is the amplitude of the sinusoidal phase voltages. In this case,
the correspondence with the motor phase voltages in SI units i.e. [V] is:
] IU [ command Voltage
Vdc .
] V [ command Voltage

1 1
where Vdc – is the drive power supply voltage expressed in [V].
In case of
brushless
motors driven in
trapezoidal
mode, the voltage command is the voltage to
apply between 2 of the motor phases, according with Hall signals values. In this case, the
correspondence with the voltage applied in SI units i.e. [V] is:
] IU [ command Voltage
Vdc
] V [ command Voltage
× =
32767
This correspondence is akso available for
DC brushed
motors which have the voltage command
internal units as the brushless motors driven in trapezoidal mode.
6.7. Voltage measurement units
The internal voltage measurement units refer to the drive V
MOT
supply voltage. The
correspondence with the supply voltage in [V] is:
] IU [ measured _ Voltage
urable VdcMaxMeas
] V [ measured _ Voltage
× =
65520
where VdcMaxMeasurable – is the maximum measurable DC voltage expressed in [V]. You can
read this value in the “Drive Info” dialogue, which can be opened from the “Drive Setup”.
Remark:
the voltage measurement units occur in the scaling of the over voltage and under
voltage protections and the supply voltage measurement
