8.4 Pulse Motor Parameters
How to Understand Pulse Motor Parameter
Example of pulse motor parameter
HSPD
LSPD
Pulse count (P)
Operating direction and operating pulse count.
Negative quantity: CCW direction
No sign (equivalent to positive quantity): CW direction
HSPD (high-speed), LSPD (low-speed)
Maximum speed and minimum speed. If they differ, slow-up or slow-down control is
performed (trapezoidal driving).
UP (rise-time), DN (fall-time)
Acceleration and deceleration time during trapezoidal driving. It is set in msec.
Delay (powerdown-delay)
A setup value, from stop to issuance of a next operating instruction.
Its unit is 2 msec. "5" in the Delay column means 10 msec.
H/L (halt-limit)
It corresponds to three digits of bits.
• 1st digit (bit 2): 0 = drive with high power; 1 = drive with low power
• 2nd digit (bit 1): 0 = stop in energized condition; 1 = stop with unenergized condition
• 3rd digit (bit 0): 0 = with power down delay; 1 = without power down delay
The meanings of the H/L values are summarized in the table below.
