53.INPUT DEBOUNCE VALUE

USE PARAMETER #53 TO SET THE LENGTH OF TIME AN INPUT MUST BE ACTIVE TO BE ACTED UPON.

RANGE OF VALUES: 0000 0000h to 0000 00FFh

0 to 256

(decimal)

Default Value: 0000 0001h

1 (decimal)

Parameter #53 is the length of time, in 10 milliseconds (1 millisecond =.01 second), that a digital input must be active before it is considered legitimate. It is used primarily to eliminate the contact bounce (which may generate multiple commands) from relays used on inputs, but it can also prevent noise problems from push-buttons.

55.MINIMUM RATIO

USE PARAMETER #55 TO SET THE LENGTH OF TIME AN INPUT MUST BE ACTIVE TO BE ACTED UPON.

RANGE OF VALUES: 0000 0000h to 0001 869Fh 0 to 99,999 (decimal)

Default Value: 0000 0000h

0 (decimal)

Parameter #55 is the minimum ratio allowed at any time in SLAVE mode.

NOTE THAT THE RATIO CANNOT GO BELOW THIS VALUE, EVEN IN RESPONSE TO DOWN FUNCTIONS OR WHEN THE FLOAT PARAMETER IS SET. This parameter must be set with these restrictions in mind.

54.FLOAT OR FREEZE

USE PARAMETER #54 TO SELECT WHERE THE SETPOINT WILL BE ON START-UP.

RANGE OF VALUES: 0000 0000h to 0000 0001h

0 to 1

(decimal)

Default Value: 0000 0000h

0 (decimal)

When parameter #54 is set to 0000 0000h, the SETPOINT at start-up (whether after a stop or after a power loss) is always at zero. The speed SETPOINT “floats” down with the motor speed. A new speed SETPOINT must be entered or the UP MOP function may be used to set speed.

When parameter #54 is set to 0000 0001h, the SETPOINT at stop or power loss is “frozen” at the current value, and the DFS-1 will return to this speed when the drive next starts up. It is not necessary to enter a new SETPOINT on start-up if a return to the previous speed is desired.

Parameter #54 also affects the SLAVE mode, but the SETPOINT cannot go to less than the value of the minimum ratio (parameter #55) in FLOAT mode.

56.COMMUNICATIONS TURNAROUND DELAY

SETS THE # OF 500 MICROSECOND DELAYS FROM TRANSFER TO TRANSMIT

RANGE OF VALUES: 0000 0000h to 0000 007Fh 0 to 128 (decimal

57.MASTER JOG SPEED

USE PARAMETER #57 TO SET A JOG SPEED WHICH CAN BE TOGGLED IN AND OUT. RANGE OF VALUES: FFFE 7961h to 0001 869Fh

-99,999 to 99,999

(decimal)

Default Value: 0000 00C8h

100 (decimal)

The MASTER JOG Speed is the speed to which the motor will go when a JOG input is activated on one of the Digital inputs (any of the seven digital inputs may be programmed as a JOG input) when the DFS-1 is in the MASTER mode. If more than one input is programmed as a JOG input, they must both be present to activate the Master Jog Speed function (the inputs are logically ANDed).
