Factory configuration
Drive factory settings
The ER12 is factory-set for the most common operating conditions (motor rating according to drive rating):
• Display: drive ready (rdY) motor stopped or motor frequency reference while running
• Automatic adaptation of the deceleration ramp in the event of overvoltage on braking.
• No automatic restarting after a detected fault is cleared
• Logic inputs:
- LI1: forward (2-wire transitional control), start drive
- LI2, LI3, LI4: no assignment
• Logic output: LO1: no assignment
• Analog input: AI1 (0 to + 5 V) speed reference
• Relay R1: the contact opens in the event of a detected fault (or drive off)
• Analog output AO1: no assignment
If the above values are compatible with the application, the drive can be used without changing the settings.
Drive factory wiring diagram
(1) R1 relay contacts, for remote indication of the drive status.
(2) Internal + 24 V DC. If an external source is used (+ 30 V DC maximum), connect the 0 V of the source to the COM terminal, and do not
use the + 24 V DC terminal on the drive.
(3) Reference potentiometer SZ1RV1202 (2.2 k
Ω) or similar (10 kΩ maximum).
(4) Forward
