1.3 Normal operation
The inverter goes into the ready-to-run state within one second after the power supply is connected. During running
the inverter follows the operator’s speed reference according to the set acceleration/deceleration ramp. During
direction change the brake is kept open all the time. When drive command is switched off the inverter decelerates
to zero according to the set ramp and closes the mechanical brake.
1.4 Status indication leds (green and red)
The inverter indicates its operating state by two leds. Red led indicates “fault state” (driving is inhibited). Green led
indicates “ok-state”. Blinking of green led indicates that fault state has been active, but it has been recovered.
Normal driving is however possible also when green led is blinking (in other words, blinking of green led does not
indicate “warning-state”).
1.5 Compact brake motors
This inverter is used with Compact brake motors, which have been especially designed for this use. The Compact
brake motors have the following special features:
Compact brake, which is opened by the magnetic force of the motor. When the magnetic force is removed (by
cutting off the motor current) the brake is closed by spring force.
High nominal frequency (80Hz…120Hz)
1.6 Programming switches
WARNING!!! There are high voltages inside the inverter (including the programming
switches). Wait for at least three minutes after the supply voltage has been switched
off before any service actions.
The programming of the inverter is performed by dip-switches. The state of each switch is either OFF (0) or ON (1).
There are five parameters that are possible to set by the switches S1-S4.
