<Description>
• Current command pulse frequency control register
• Displays the control value of the current command pulse frequency.
• The function of the current frequency register differs depending on whether automatic acceleration/deceleration is
enabled or disabled.
Points of use:
· Enabling/disabling of automatic acceleration/deceleration is determined by the setting of the control register
(parameter No. 15).
· Do not write data in the current frequency register.
If data is written in the current frequency register, the processing for acceleration/deceleration is not executed.
1) When automatic acceleration/deceleration is enabled
• This module automatically sets the current speed value in the current frequency register.
• When command pulse output is stopped, the current frequency register is cleared to zero.
(While pulse is being output, the control value of the current command pulse frequency is set.)
• At the rising edge of the start signal, the set value of the base frequency register is copied in this area.
• When constant speed is reached after the end of acceleration/deceleration, the setting of this register becomes
equal to that of the target frequency register (or the base frequency register).
• The processing for acceleration/deceleration is performed based on the current value of the current frequency
register and the content of the command pulse register, deceleration point register, target frequency register and
base frequency register.
The processing for acceleration/deceleration is as follows:
When command pulse register > deceleration point register
Accelerates if
current frequency register < target frequency register
Decelerates if
current frequency register > target frequency register
Constant speed if current frequency register = target frequency register
When command pulse register < deceleration point register
Accelerates if
current frequency register < base frequency register
Decelerates if
current frequency register > base frequency register
Constant speed if current frequency register = base frequency register
When command pulse register = deceleration point register
Current command frequency is held
Besides, when the deceleration-and-stop or quick stop command is received, operation is decelerated as follows:
Decelerates if current frequency register > base frequency register
Command pulse output is stopped if current frequency register
≤
base frequency register
