1. Basic connection
Wiring options
There are two wiring methods:
- NPN type (such as opening a switch)
- PNP type (such as closing a switch)
Important! When using an external power supply:
- Never connect 24V and 0V wires together
- Double check the + and - wiring to avoid damage
Speed Control Wiring
- Use the AI1 or AI2 ports
- These ports accept:
- Voltage signals (0-10V)
- Current signals (4-20mA)
- Always use shielded cables (such as TV antenna cables) to prevent interference
2. Setting up your inverter
First time setup
-Factory reset:
- Set P0010 = 30
- Then set P0970 = 1
-Quick setup mode (P0010 = 1)
-Enter your motor details (such as nameplate information)
-Select Terminal Control (P0700 = 2)
Speed Control Setup
P0756: Signal that tells the inverter what you are using:
0 = 0-10V knob
3 = 4-20mA Dial
P0775: Reverse operation:
Set to 1 to see the actual speed when running in reverse
P1000: Set to 2 to use analog input for speed control
3. Use preset configuration
- Siemens provides ready-made settings called "Connection Macros"
- Important: Always reset before changing macros
- If you do not reset, the inverter may malfunction and behave abnormally
4. Common problems and solutions
- No response to speed control?
- Check if P0756 matches your control type
- Test with a multimeter whether the signal is reaching
- Speed display is wrong when reversing?
- Set P0775 = 1
- Check if there are loose wires or electrical noise
5. Useful tips
- Always test at low speed first
- Use high-quality shielded cables
- Save settings after setting
- Check connections regularly
