Functions
You can configure the signal relays to be activated when the
product changes to one of the following states:
• Not active
The relay has been deactivated.
• Ready
The motor may be running or is ready to run, and no alarms are
active.
• Alarm
There is an active alarm, and the motor is stopped.
• Operating (Operation)
Operating equals Running, but the motor is still in operation
when it is stopped, for example, by the Stop function or Limit
exceeded.
• Running (Pump running)
The motor shaft is rotating.
• Warning
There is an active warning.
• Limit 1 exceeded
When you have set this function and the limit is exceeded, the
signal relay is activated.
• Limit 2 exceeded
When you have set this function and the limit is exceeded, the
signal relay is activated.
• External fan control (Control of external fan)
When you select this function, the relay is activated if the
internal temperature of the motor electronics reaches a preset
limit value. In this way the relay activates external cooling to add
additional cooling to the motor.
• Digital input 1, state
Follow digital input 1. If digital input 1 is triggered, the digital
output is also triggered.
• Digital input 2, state
Follow digital input 2. If digital input 2 is triggered, the digital
output is also triggered.
•
Digital input 3, state
Follow digital input 3. If digital input 3 is triggered, the digital
output is also triggered.
• Digital input 4, state
Follow digital input 4. If digital input 4 is triggered, the digital
output is also triggered.
10.14 Analog output
The inputs and outputs available depend on the functional module
fitted in the motor.
