7. COMMISSIONING
- Check the connection of the following items :
- transformer
- relay system, especially the emergency stop
- motor and any smoothing choke
- tachometer system
- ground circuit
- Speed and current inhibited (X1/10 and X1/11 not connected),
Connect the power to the servo amplifier. The "POWER ON" LED should light up (if
not check the transformer wiring and relay system). If the "POWER ON" LED flashes,
measure the transformer secondary voltage :
RTS 10/20 - 60 Us = 48 vac : 43 vac < Usec < 53 vac
RTS 3/10 - 40 M Us = 32 vac : 29 vac < Usec < 35 vac
RTS 12/24 - 130 T Us = 100 vac : 90 vac < Usec < 110 vac
RTS 13/32 - 190 T Us = 135 vac : 122 vac < Usec < 148 vac
RTS 20/40 - 130 T Us = 100 vac : 90 vac < Usec < 110 vac
Adjust the output voltage as required with the ± 5% transformer terminals.
- With zero speed reference (X1/4 = X1/5 = 0V)
Release the servo amplifier (X1/10 and X1/11 at 0V), the motor must be under torque.
If the motor races, cut the power and check the signals from the tachometer (cut-out or
inversion) before switching on again ("TAC" fault). If the motor "growls" or "vibrates"
with possibly an "IFT" fault, reduce servo amplifier gain by turning the front panel
potentiometer anti-clockwise. If the servo amplifier had switched to fault mode
("POWER ON" flashing) use RESET (X1/12 to 0V) to clear the fault.
- Gradually increase servo amplifier reference,
and monitor motor acceleration. Check the motor rotates in the opposite direction
when the reference is reversed. If a fault arises on inversion for a 10 V reference,
adjust servo amplifier gain (see paragraph : gain adjustment).
If the fault persists, wire the power transformer secondary to the -5% terminals ("MAU"
fault on LED strip).
