*1) Control power (24V, G24V) and power for I/O (COM+, COM-) must share one common power supply.
*2) When driving a load containing inductance ( component such as
a
relay ) connect a protection circuit (diode).
The motor brake cannot be driven directly. Be sure to use a circuit that interfaces with a diode built-in type relay.
Page 46 Connection to general-purpose output signals
*3) The output circuit configuration is an open collector Darlington transistor output. Connects to relays and optical isolators.
Note that when the transistor is on, connector-emitter voltage VCE (SAT) is approximately 1V;
a standard TTL IC does not satisfy VIL and cannot be connected directly.
*4) Be sure to connect a termination resistor of approximately 220 Ω .
*5) Make the connection to the communication IC signal ground of the host controller that
the drive
encoder output signals
are connecting to. Connecting signal ground SG to control power GND may result in malfunction.
*6) If Z-phase pulse width is too small to be measured accurately by the host controller, decrease pulse division rate by using pulse output
ratio (parameters No.276.0 and No.278,0) or decrease rotational speed to increase the pulse width.
Pulse width [ms] = 2 / rotational speed [
rpm
] / (division ratio × 2
17
) × 60 × 1,000.
