Ratings of the contact input terminals
Input resistance: 4.7k
Ω
, open-time voltage: 24
±
3VDC, short circuit-time current: 4 to
6mADC
Use the terminal PC as a power supply terminal.
Can be used as a power supply for a sensor or equivalent. The common terminal is
the terminal SD (digital common).
Power supply voltage range: 24
±
2VDC, max. permissible current: 100mA
When the terminal is used as a power supply, it cannot be used as an external
transistor common terminal to prevent a sneak current.
The response time of the contact input terminal is 20ms
±
15ms. (When the stall
prevention function is activated, response may be slower.)
NOTICE
When a transistor is used to input the signal of the contact input terminal, make sure
that the electrical characteristics of the transistor used satisfy the following:
I
C
: Collector current, 10mA or more
V
CEX
: Open-time collector-emitter permissible voltage, 30V or more
V
CE(sat)
: Conduction-time collector-emitter saturation voltage, 3V or less
I
CEX
: Collector shutoff current (leakage current), 100uA or less
When a relay contact is used to input the signal of the contact input terminal, use
two faint signal contacts in parallel or use a twin contact to prevent a contact fault.
(2) Speed command input terminals
Terminals used to vary the motor speed with analog signals.
The parameter function allows you to choose the analog speed command specifications.
