1. This parameter specifies the feedforward gain of position loop.
2. Setting the value to 100 % means position hysteresis is always 0 at any pulse command frequency.
3. Increasing the feedforward gain of position loop improves the high-speed response characteristics of
the control system, but meanwhile causes the system's position loop unstable and liable to oscillation.
4. Unless very high response characteristics are necessary, set the feedforward gain of position loop to 0
This parameter specifies the maximum possible following error. When the actual following error is larger than
the setpoint, the drive sends an over-position alarm (A43)
When the drive is enabled, the drive brake will be opened after a delay which is set by P41.
Drive can be enabled under the following conditions:
A:
When the following three conditions are all met:
1. Terminal 65 (external enable) has been enabled;
2. The drive has received an enable signal from NC;
3. No alarm is detected by the drive.
B:
When the following two conditions are both met:
1. Terminal 65 (control enable) has been activated;
2. Motor operates in "JOG-RUN" mode (enabled from function menu )
C:
When the following two conditions are both met:
1. P05 = 1 (The JOG mode can be enabled internally);
2. Motor operates in "JOG-RUN' mode (enabled from function menu )
When motor speed exceeds 30 rpm and the drive generates an alarm, if, within the specified brake close time
(P42),the actual motor speed becomes smaller than the P43 setpoint, brake is closed when the actual speed
reaches the speed P43 sets.
This parameter specifies the input pulse multiplier. For example, when P36 = 100, input frequency = 1 kHz,
output frequency = 1 kHz x 100 = 100 kHz.
When motor speed exceeds 30 rpm and the drive generates an alarm, if, within the specified brake close
time (P42), actual motor speed remains bigger than brake close speed setpoint (P43), brake is closed after
the specified brake close time (P42) expires.
When motor speed is lower than 30 rpm, the drive remains enabled within the time period set by P44
after brake close.
This parameter specifies the motor speed in JOG mode.
This parameter defines the time period when the motor ramps up from 0 rpm to 2,000 rpm or ramps down
from 2, 000 rpm to 0 rpm.
Reserved for Siemens internal use only
Note:
Pulse frequency setpoint = Actual pulse frequency x input pulse multiplier;
This parameter is applicable only when the software version is V01.06 or later;
When P36 = 100 or 1,000, speed stability will decrease with higher multiplication factor.
