Speed reference
- Analogue reference (0 V or 4 mA = min. speed)
(10 V or 20 mA = max. speed)
- 0 - 10 V with built-in potentiometer
- 0 - 10V with remote potentiometer option*
- 0 - 10 V with external reference*
- 4 - 20 mA with external reference*
• Digital reference
- 1 to 3 preset speeds (accessible with the parameter-setting option**)
Speed regulation
Regulation of a reference with the integrated PI loop (accessible with the parameter-
setting option**)
PI sensor characteristic: 0 - 10 V signal
Run/Stop
• With 3-phase power supply (max. 10 per hour)
• With remote volt-free contact
Forward/Reverse
• With internal connection on the terminal block
• With remote volt-free contact
Stop mode
• On ramp (with volt-free contact or integrated Run/Stop command)
• Freewheel stop (by cutting the 3-phase power supply)
• Freewheel stop (with volt-free contact) - (accessible with parameter-setting
option**)
Ramps
• Selection of acceleration and deceleration ramps with volt-free contact: 2 s or 10 s
(factory setting 10 s for F max 80 Hz)
• Ramps adjustable from 0 to 20 s (accessible with the parameter-setting option**)
INDICATIONS
VARMECA 14
Display
Indicator lamp
• Permanent green light: mains connected
• Flashing green light: current limit
• Permanent or flashing orange light: overload
• Flashing red light: under/overvoltage fault
• Permanent red light: other fault
Relays
• Volt-free contact - 1 A - 250 V
- volt-free contact open: drive faulty or drive switched off
Analogue output
• Speed signal 0 - 10 V, 3 mA
• 0 V = zero speed / 10 V = max. speed
* Adjust using mini-DIP switch (see section 2.3)
** See VARMECA 10 manual - Parameter-setting.
