VFDs - Technical Details
Enhanced Function
| Time- Delay relay | Simple logic programming for the multi-functional output terminals and the digital input terminals. The logic results can be equivalent to the digital input terminal function, and can be output through the multi-functional output terminals |
|
Internal Timer |
Two internal timers to collect timing input signals and to output timing signals. The two timers can be used separately or together |
|
Internal math operator module |
One internal 4-way math module for elementary arithmetic operations, numerical magnitude judgment and integral operation |
Communication
| E100 |
The control panel has a RS485 communication interface which supports standard MODBUS-RTU protocol |
| E102/ E180/ EM60 |
The control panel does not have a RS485 communication interface, and an external 485 communication expansion card shall be connected. Support standard MODBUS-RTU protocol. The E180 series also support standard PROFIBUS-DP protocol (through an external E180-DP expansion card) |
Coder
| E100 |
The coder can be connected directly through the DI5 and DI6 terminals on the control panel, and simple closed-loop control is available through PID control. Such connection is used in undemanding situations |
| EM60 | The control panel does not have any interface for the coder, and a one-way high-speed pulser can be extended (through DI6) |
| E102 | The control panel only has one coder interface (DI6) |
| E180 |
The control panel does not have any coder interface, and an external coder expansion card is necessary. The inverter supports ABZ incremental coder, UVW incremental coder and resolver. Such connection enables high-performance VC, and can be used in situations with demanding control precision requirements |
Motor
| E100/E102 | Only for asynchronous motors |
| E180 | For asynchronous motors and synchronous motors |
Display
| Operation Information | Given frequency, output frequency, output voltage, busbar voltage, input signal, feedback value, module temperature, and synchronous speed of the motor. At most 32 parameters can be displayed in cycle through the “>>” key |
Protection
| Inverter Protection | Over-current, over-voltage, module fault protection, under-voltage, overheat, overload, external fault protection, EEPROM fault protection, ground protection, and default phase |
| Inverter Alarm | Locked-rotor protection, overload alarm |
| Instantaneous Power Down | Less than 15ms: continuous operation More than 15ms: automatic restart |
