Does LS offer any solution for winder and web applications?
Yes, depending on the complexity of the winder or web, an S100 or iS7 may be used. Contact your local sales person for more information on which may be the right choice for your application. You can also refer to the attached file for more details of ...
What are the difference between Sensorless-1 and Sensorless-2 for the iS7?
The main difference is the method which is used for the Speed Estimation. For higher torque or more precise applications, it is recommended to use Sensorless-2 Sensorless-1 estimates the motor speed with a simple equation. Sensorless-2 estimates the ...
What is a DB unit?
What is DB ? "DB" stands for dynamic braking. Applications with high inertia, regenerative loads, cyclic loads, or any application with "regen energy" may require dynamic braking. Dynamic braking uses a transistor and a resistor to absorb this ...
What are the differences between Flying Start-1 and Flying Start-2 in iS7
1. Flying Start-1 - Older method for Speed Search. - Speed search is implemented by controlling the output current at or below the speed search current(CON-72) value. - Advantage : Stable at the low speed below 10Hz if the direction is same. - ...
How do I set a high (over 60Hz) max frequency on the C100?
There are a few parameters which are required to overspeed the VFD past 60Hz. First off, you will need to change the VFD maximum speed limits. Next, you need to scale your analog input (if used). If you are using the keypad for frequency control, you ...
What are the minimum clearances for the H100 VFD?
What impedance is the built-in DC reactor?
LS VFDs that have a built-in reactor are rated at 3% impedance.
Are VFD keypads interchangable?
It depends on the series of VFD. Currently, the only keypad (also called a loader) that is interchangeable is the S100/iS7 one. The H100's keypad only works on H100's. The M100 and G100 both have remote keypad options also, but they are not ...
Does LS offer a NEMA 4X rated keypad?
The remote LCD keypad is not NEMA 4X rated. Alternatively, you can order a remote keypad mount which is NEMA 4X rated. Below is a sample parts list of the parts needed. LS NEMA4X keypad mount This is an S100 IP20 VFD but has all the accessories for ...
What are the specifications of the internal brake chopper?
All LS VFDs up to 30 HP have a built-in braking transistor(also called a chopper). The internal brake chopper is rated at 150% braking torque. Duty cycle can be up to 15% (15sec/100sec).
Pinout for RS-232 DriveView 9 Cable (H100, H100+, S100, iS7)
Under certain circumstances, it may be necessary to obtain the pinout for the RS-232 DriveView 9 cable used for H100, H100+, S100, and iS7 drives. The order code for the pre-made cable is # 76676236322. 9-Pin Sub-D Connector Pin # RJ-45 Connector Pin ...
Does the M100 have a NEMA 1 conduit kit option?
No, it does not. The M100 has an IP20/ UL Open Type rating. To meets NEMA 1 ratings the VFD would need to be put in a panel.
How do I set the VFD capacity after changing the control PCB on the iS7?
What size eye-bolts can I use on larger H100s?
The larger capacity (>110kW) H100 drives may require a crane or hoist to lift it into place. The H100 features two mounting options; lifting holes and eye-bolts. Please note, lifting eye-bolts are not included in the H100 package. Below is a list of ...
Setting a password on the G100 and S100 VFDs
The G100 and S100 can be locked out via password protection. Setting up a password will prevent unauthorized parameter changes. Setting the Password 1. Navigate to Dr.94 2. Press ENT key two times 3. Set desired ...
How can I make my external trip to the VFD normally closed?
By default the external trip or BX function on the digital inputs are Normally Open (N.O.). Any of the digital input can be easily inverted to be a Normally Closed (N.C.) type at In87. Moving the "DIP Switch" to the up position makes the ...
Parameters are not saving when set over DriveView9
Parameters written over DriveView9 are saves to volatile memory. Therefore, after a power loss the changed parameters will no be saved. So ensure parameters are saved be sure to use the "EEPRom Save" button (pictured below). This will save all ...
How to I access advanced parameters on the M100?
By default only the Operation group of parameters is available on the M100. To access the other groups you must navigate to the OGr parameter and set it to a 1.
How do I run my motor faster than 60Hz?
Some applications require that the motor runs faster than 60Hz. By default LSIS VFDs limit speed to 60Hz. To increase this, see the below parameters. G100, S100, iS7, and H100 Setup dr/DRV20 = Desired Maximum Frequency Ad/ADV24 = Minimum/ ...
How do I setup my VFD for an HOA switch?
