Explanation: 1. SRV-CTRL refers to the servo control module of PLC;
2. Take the → pointer as input and the ← pointer as output.
3. The meanings of each signal are as follows:
INH: Prohibit input of pulse commands (prohibited when open circuit);
OZ -: Z-phase output;
OZ+: Z-phase output;
S-RDY: The servo drive is ready;
ALM: Servo drive fault alarm;
COIN: Positioning completed;
SRV-ON: servo drive “on” signal;
COM -: Negative pole of power supply;
COM+: Positive pole of power supply;
PULS1: Command pulse input terminal;
PULS2: Command pulse input terminal;
SIGN1: Command pulse symbol input terminal;
SIGN2: Command pulse symbol input terminal;
Servo Drive Wiring Guide
In the field of industrial control automation, many devices have strict installation specifications. So, in order to avoid usage
risks and eliminate safety hazards, what are the rules for connecting servo drives?
1. It is recommended to use a three-phase isolation transformer for power supply to reduce the possibility of electric shock.
2. It is recommended to use a noise filter for power supply to improve anti-interference ability.
3. Please install a non melting short-circuit circuit breaker to promptly cut off external power in case of driver failure.
4. The grounding wire should be ≥ 2.5m2, as thick as possible, and made into a single point grounding.
The grounding terminal of the servo motor must be connected to the grounding terminal PE of the driver.
5. Connect the shielding layer of the cable correctly.
To prevent interference and misoperation, it is recommended to install a noise filter and pay attention to:
(1) The noise filter, servo drive, and upper controller should be installed as close as possible.
(2) Surge suppressors must be installed in relays, AC contactors, brakes, and other coils.
(3) Power circuit cables and signal lines should not be tied together.
