Brake Delay Timers; Timer Function - Magnetek Impulse G+ series 4 Instruction Manual

Brake Delay Timers

This function is used in trolley or bridge applications. It can reduce the mechanical brake wear when
the operator tries to position a load. This function is available only in traverse mode and the constant
B03-03 must be set to 4 (Decel With Timer).

NOTE: The Jog control input is a multi-function input. It is enabled by programming H01-01–08 =
15 or 16.

Timer Function

• The timer function is enabled when the timer function MFDI (H01-0x = 43) and the timer function
MFDO (H02-0x = 12) are set respectively.
• The input and output serve as general purpose I/O. Chattering of sensors, switches, contactors,
etc., can be prevented by setting a delay time.
• When the timer function input ON time is longer than the value set for C12-03 (Timer function
ON-Delay Time), the timer function output turns ON.
• When the timer function input OFF time is longer than the value set for C12-04 (Timer function
OFF-Delay Time), the timer function output turns OFF.

C12-03* Delay-ON timer
C12-04* Delay-OFF timer
* This function is enabled when timer function is set to MFDI/MFDO; H01-xx=43, H02-xx=12.
