Example
:
Motor 200 step/turn, set at a quarter step.
Start-up frequency set at 500 Hertz
Corresponding turns = 37.5 r.p.m.
since the stepping-stepping motor features a torque that reduces with the speed
the a correct selection of this value makes the best of the motor characteristics.
4° e 5° Byte (Frequenza massima)
The scope of this byte is to set the maximum frequency corresponding to motor
running speed. The set value is in Hertz, maximum value is 20000 Hertz.
The same considerations made for the minimum frequency apply. For the same
reason, maximum frequency must not exceed the speed value at which the motor
maintains a useful torque; a stall fault would otherwise occur resulting in loss of
position.
6° e 7° Byte (Ramp Time)
The scope of this byte is to set motor acceleration and deceleration times in milli-
seconds which is the time value necessary to pass from minimum to maximum
speed.
A too short a value could cause a stall fault; on the other hand an excessive value
could enhance resonance phenomena, both electrical and mechanical, which
could also cause stall faults.
A correct value allows a load/motor to accelerate and the system inertia allows
speeds at which the system resonates without entering a stall condition.
ID 706h (Options)
This control serves to set some board operation options. These are PERMANENT op-
tions which means that they will still be in place even without power supply; they are
normally used in the board installation phase.
It will be possible to change these options at least 100 times.
1°Byte (Option 1)
There are five fields:
1st field
: LCD, refers to the possible use of a liquid-crystal display connected to the
appropriate port.
Set at 1 the appropriate display is connected - set at 0 the display in not available
2ndfield
: refers to the board-mounted LED operation modes:
• 00: Status display of Home sensor.
• 01: flashing at 1 Hz indicating board operation.
• 10: motor status; on = in movement , off = stopped
• 11:receipt of a valid CAN frame.
3rd field
: possibility of moving upwards the addresses of the board output frames by a
value equal to 0x80 when the field is set at 1.
