3 — PROGRAMMABLE PARAMETERS: Electromagnetic Brake Parameters
Table 3 CONFIGURATION OPTIONS:
AUXILIARY DRIVER (Pin 8)
TYPE DESCRIPTION OF OPERATION
0 Aux driver disabled.
1 Electromagnetic brake used like a parking brake.
• The brake is released when the interlock switch closes.
• The brake is engaged as follows:
Interlock The aux driver engages the brake when the interlock switch opens
and (a) the programmed Sequencing Delay and Interlock Brake Delay expire
or (b) the motor speed nears zero, whichever happens first.
Neutral State * The aux driver does not respond to neutral state; there is no
therefore no Aux Delay.
Emerg. Rev. The aux driver does not respond to emergency reverse.
2 Electromagnetic brake used to prevent rolling when stopping on a hill.
• The brake is released when the interlock switch closes
and either a direction switch or the emergency reverse switch closes.
• The brake is engaged as follows:
Interlock Same as Type 1.
Neutral State * When the vehicle reaches the neutral state, the aux driver
engages the brake as soon as the programmed Aux Delay expires.
Emerg. Rev. After the emergency reverse switch has been applied and
released, the aux driver engages the brake as soon as the programmed Aux
Delay has expired. The Aux Delay timer starts when motor speed nears zero.
3 Electromagnetic brake functions as in Type 2 except during Emerg. Rev.
Emerg. Rev. (a) If both direction switches are open when the emergency
reverse switch is released, same as Type 2. (b) If a direction switch is closed
when the emergency reverse switch is released, the Aux Delay timer starts
when the emergency reverse switch is released.
4 Electromagnetic brake functions as in Type 1 except during Emerg. Rev.
Emerg. Rev. Same as Type 3, except in situation (a), where the aux driver
does not respond, and the brake therefore remains released.
5 Auxiliary device other than an electromagnetic brake.
This option is appropriate if the aux driver will be used for a brush or pump
motor contactor, for example, or for hydraulic steering assist. The aux driver
will be energized when the interlock switch and either a direction switch or
the emergency reverse switch are closed. The aux driver will turn off when
the programmed Aux Delay has expired after the interlock switch opens, or
both direction switches are opened while the vehicle is driving, or the emer-
gency reverse switch is released. The Aux Delay timer starts when motor
speed nears zero.
* The neutral state is reached when, during normal operation, the throttle is in neutral, no direc-
tion is selected (both direction switches open), and motor speed is approximately zero.
