Connection of encoder with +12 V supply.
U VERY IMPORTANT
It is necessary to specify in the commercial order the type of encoder used, in
terms of power supply, electronic output and n° of pulses for revolution,
because the logic unit must be set in the correct way by Zapi.
6.2.6 Connection of a Sin/Cos sensor
When the PMSM is of the BLAC type, must be controlled with sine waves shape. A
PMSM is a BLAC when, by turning its shaft lightened, the electromotive force
between two motor terminals is of the shape sinusoidal.
To control PMAC motor with Zapi inverter, it is necessary to install an absolute
Sin/Cos sensor. The Sin/Cos sensor power supply can be +5 or +12 V. At the first
key an auto-teaching procedure it is necessary to permit to the controller to acquire
the sensor signals.
B8 +5V/+12V positive supply.
B15 GND negative supply.
B7 SIN sine signal.
B14 COS cosine signal.
Connection of sin/cos sensors.
U VERY IMPORTANT
It is necessary to specify in the commercial order the type of sensor used, in
terms of power supply, electronic output and n° of pulses for revolution,
because the logic unit and the software must be set in the correct way by Zapi
lines.
