Pulse engine status/control dialog parts

1. Main Pulse engine settings:

a. Enable pulse engine: main switch to enable or disable Pulse engine functionality

b. Lock: when Lock is enabled, the main Pulse engine settings and Pulse generator

settings are disabled

c. Enable safety charge pump output: configure the pin for the charge pump output

d. Invert emergency input polarity: PoKeys expects NC (normally closed switch to be

used as emergency switch) and HIGH signal state on emergency input indicates an

emergency. If NO switch is used, the polarity of the signal must be inverted by

selecting this option

e. Enable backlash compensation: check this option to enable the backlash

compensation in PoKeys device.

2. Pulse generator options: PoKeys57CNC contains an external pulse generator on-board, thus

external pulse generator option with ‘Extended IO’ must be selected. Up to 8 axes can be

enabled

3. Axis configuration - see next page

4. Pulse engine state display and control: this panel displays current PoKeys Pulse engine state

and allows the user to change between the states

a. STOP: stopped mode - the Pulse engine is deactivated momentarily and produces no

pulses. Transition to STOP mode is instantaneous - if there is any motion being

executed, the pulse generation will cease immediately after switching to STOP mode.

b. ERR: error mode - if PoKeys detects any event that results in error (emergency stop,

limit stop, etc.), this mode will automatically be activated. As STOP mode, the

transition is instantaneous

c. Homing: in this mode, PoKeys is executing the homing procedure. The selected axes

are referenced in regards to the position of Home/Ref switch. PoKeys executes

homing procedure in two steps - in first step, course position of the switch is located

using faster motion in the negative direction of the axes (unless Homing direction is

inverted in the settings). When the switch is located, the fine position of the

reference position is located using slower motion in the positive direction of the axis

(again, if not inverted in the settings) until the Home/Ref switch is released.

d. Running: normal operating mode

e. Jogging: jogging mode - in this mode, PoKeys Pulse engine can use the values from

the encoders to directly jog the configured axes

f. Emergency: this field indicates whether device entered Emergency state

g. Limit override: switch that allows the user to activate the limit override

5. Enable axis power and enable charge pump: these options select, when the axis enable and

chargepump output signals are activated (besides normal operating modes)

6. Save configuration button: after the settings are changes, this button must be clicked to

send the settings to device and save them to the on-board non-volatile memory. Since this

operation may produce interruptions in the motion, it is suggested to stop any motion

before commencing configuration save.

7. Pulse engine testing panel:

8. Additional configuration options - here, additional configuration dialogs can be opened

9. Auxilary outputs: these can be used to test the on-board auxilary outputs
