5.2 Features
RAMO5 (Rapid Link Motor Control Unit) is an electronic motor starter for the
direct start of three-phase motors up to 6.6 A (
≥ 3 kW at 400 V). RAMO5
switches with thyristors and relays in the energy branch. This makes it possi-
ble for the units to have a lifespan of more than 10 million switching cycles.
RAMO5 is available in two versions with respect to the direction of rotation:
• RAMO5- D … = DOL starter for one operating direction
• RAMO5- W … = Reversing starter for two operating directions (FWD,
REV)
The speed of the controlled motors is constant after run-up and is deter-
mined by the frequency of the supply voltage (energy bus, 50/60 Hz).
The three-phase motor protection enables the protected operation of three-
phase motors in the range of 0.3 A (
≥ 90 W at 400 V) to 6.6 A ( ≥ 3 kW at
400 V). This enables the so-called thermistor motor protection to be imple-
mented in conjunction with the integrated thermistor monitoring.
The built-in transistor switch allows actuation of spring-loaded brakes with
DC air solenoid valve. For the brake rectifier a controlled supply voltage of
180 V AC, 230 V AC or 400 V AC is output (
￫ Figure 63, page 100).
