PG DRIVES TECHNOLOGY I-DRIVE TECHNICAL MANUAL – PROGRAMMING
2.7 Max. Reverse Speed
This parameter sets the MAXIMUM reverse speed of the machine.
So long as a Slow/Fast switch is fitted to the machine then there are two available settings.
Fast This value is used when the slow/fast switch is set to fast.
Slow This value is used when the slow/fast switch is set to slow.
The value is displayed as a percentage of the machine’s total available output. Therefore if the Fast value is set to 60% then the
machine will be able to drive at up to 60% of the total available speed when the Slow/Fast switch is in the Fast position.
This value is adjustable between 0 and 100% in steps of 1%.
If there is no Slow/Fast switch fitted then only the Fast value will be relevant.
2.8 Min. Reverse Speed
This parameter sets the MINIMUM reverse speed of the machine.
For this parameter to operate, a Speed Limiting Potentiometer must be fitted and correctly programmed. The Speed Limiting
Potentiometer must be fitted in Parallel, refer to
Chapter 2 Section 4.2. Under these conditions there are two available settings.
Fast This value is used when the machine’s Speed Limiting Potentiometer is set to Slow and the Slow/Fast switch is
set to Fast.
Slow This value is used when the machine’s Speed Limiting Potentiometer is set to Slow and the Slow/Fast switch is
set to Slow.
The value is displayed as a percentage of the machine’s total available output. Therefore if the Fast value is set to 20% then the
machine will be able to drive at up to 20% of the total available speed when the Slow/Fast switch is in the Fast position and the
Speed Limiting Potentiometer is in the Slow position.
This value is adjustable between 0 and 100% in steps of 1%.
If there is no Slow/Fast switch fitted then only the Fast value will be relevant.
This parameter cannot be set at a greater value than the Max. Reverse Speed.
2.9 Speed Limit Pot. Enabled
This parameter selects whether pin 9 is to be unused, used for a parallel type speed limiting potentiometer or configured for a
Belly Button switch. The parameter can be set to On or Off.
If set to Off, the i-Drive will not perform any potentiometer checks on pin 9.
If set to Off and
Belly Button Time is > 0, the i-Drive will operate as per the Belly Button function, see Chapter 2, Section
4.2.2
.
If set to On, then the i-Drive will check for the presence of a valid speed limiting potentiometer signal at pin 9, refer to
Chapter 2 Section 4.2. If a valid signal is not detected, the i-Drive will default to the programmed minimum speeds.
If a speed limiting potentiometer and a Belly Button switch are both required, the speed limiting
potentiometer must be wired in series with the throttle wiper input. It is the machine
manufacturer’s responsibility to ensure that any such arrangement is suitable for the intended
application.
If a parallel type speed limiting potentiometer is fitted, this parameter must be set to ON or the
machine will only drive at the maximum programmed speed settings.
