Goodrive350-19 series VFD Product overview
- 12 -
Function
Specification
Zero position
detection
The zero position signal and running signal are mutually
exclusive.
Torque verification
The VFD verifies the current or torque before brake release. The
VFD performs brake release when the verification succeeds, and
the VFD reports the verification fault when the verification fails.
One key
open/closed loop
switchover
The closed-loop control mode can be switched to the open-loop
control mode through terminals. When the encoder is faulty, the
open-loop control mode can be used. The switchover can get
response only in stopped state but not in running state.
Jogging
After receiving a jogging command, the VFD can automatically
start, run, and stop at the preset running frequency and time
according to the settings. During the process, the brake can be
normally opened or closed under the control of VFD, ensuring
the stability without hook slip or exception when the crane starts
or stops.
Smooth lifting
In high-speed lifting mode, the high speed is limited at the
moment of steel rope straightening, reducing the impact caused
by the sudden load to the hoist at the lifting start.
Set frequency
exception
protection
If the set frequency is lower than the threshold after the brake is
opened, the VFD reports the set frequency exception, which
prevents slip caused by insufficient force at low speed.
Motor overheat
protection
The I/O extension card can receive motor temperature sensor
input (PT100, PT1000 and PTC).
