PG DRIVES TECHNOLOGY I-DRIVE TECHNICAL MANUAL – PROGRAMMING
7.11 Brake Light
If the parameter
Auxiliary 2 Output Mode is set to Brake Light, this parameter must also be set to On when using i45 or i70
controllers.
The parameter can be set to On or Off.
This parameter is not required to be set when using i140 or i180 controllers.
7.12 Freewheel Speed Limit
If the solenoid brake is disconnected from the motor, allowing the wheels and motor to rotate, the i-Drive can detect the motor
rotating above a certain speed and brake it automatically, thus removing the possibility of the machine freewheeling at an
excessive speed. This function will operate if the machine is switched off and even if there are no batteries fitted or connected.
This parameter is factory set and should not require adjustment. For further details contact
PGDT.
It is the responsibility of the machine manufacturer to ensure that adequate precautions are
taken to warn the user against the hazards of freewheeling the machine at excessive speeds. It is
also the responsibility of the machine manufacturer to utilize a suitable freewheel mechanism to
reduce these risks. PGDT accepts no liability for losses of any kind resulting from excessive
freewheel speeds of a machine.
8 Motor Parameters
8.1 Current Limit
These parameters allow the maximum and minimum current limits to be altered in 1A steps, where dependencies permit.
Min. Sets the current output of the i-Drive when it is at 80°C, 10A to Current Limit Max.
Max. Sets the continuous current output of the i-Drive, 10A to 180A.
8.2 Boost Drive Current and Boost Drive Time
These parameters provide a current boost for a set length of time if the controller recognizes a drive demand that causes the
motor to require more current, such as when the machine is being driven up a gradient. Refer to the following graph.
