EM500 Open-Loop Vector Control Inverter User Manual
74
In case of ramp-to-stop, please confirm braking unit and
braking resistor have been properly connected.
Check whether inverter runs normally and whether braking
mechanism acts normally by switching forward and reverse
operations with keypad.
Observe whether inverter outputs corresponding frequency level
by level through master controller’s sending of speed signal of all
speed levels.
Independent braking unit. Please observe whether the braking unit
indicator is on.
Inverter can start, run, stop, run forward and reverse, and perform
other basic operations. In case of any abnormality, please check
whether input and start/stop function codes are correctly set.

Often used for occasions of high-inertia drive system and
occasions sensitive to acceleration to reduce mechanic shock and
avoid system vibration.
Input DC current to motor before start or stop, in order to generate
braking torque and thus rapidly stop the rotating motor.
With multiple multi-function input and output ports, EM500 can
offer various kinds of application solution when in use with
external controller.
1. It’s strongly recommended to execute the trial operation with keypad under
terminal or communication control application.
2. Inverter can be used normally only after it has passed the idle trial operation and the
full-load trial operation.
5.2 Attentions for Trial Operation
5.2.1 Turn on the Power Switch
Before turning on the power switch, please confirm the following items:
Correct power voltage: 3-phase AC380 - 415V or 3-phase/single-phase
AC220 – 230V, 50Hz
